The concept of a reduction between subsets of a given space is described, giving rise to various complexity hierarchies, studied both in descriptive set theory and in automata theory. We discuss in particular the Wadge and Lipschitz hierarchies for subsets of the Baire and Cantor spaces and the hierarchy of Borel reducibility for finitary relations on standard Borel spaces. The notions of Wadge and Lipschitz reductions are related to corresponding perfect information games.

Opis:
Zaprezentowano metodę wyboru strategii w dwuosobowej, sekwencyjnej grze rynkowej, w której gracze są zmuszeni zarówno konkurować, jak i kooperować. Założono obustronną i wzajemną znajomość macierzy wypłat oraz celu, który gracze chcą osiągnąć. Przyjęto, że decyzja o charakterze konkurencyjnym danego gracza poprzedza decyzję o charakterze kooperacji oraz konkurencyjną odpowiedź drugiego gracza. Zaproponowano przykład zastosowania metody w rozwiązaniu problemu wyboru strategii cen detalicznych na lokalnym rynku usług telekomunikacyjnych, w perspektywie konieczności nawiązania współpracy międzyoperatorskiej oraz odpowiedzi na rynku detalicznym konkurencyjnego gracza.
Method of choosing strategy in two persons, sequential market game, when players are forced so to compete as to cooperate was presented. It was assumed that players know their own and the other player pay off matrix as well as the goal that the other aims to realize. The decision of competitive character precedes the cooperative one, and the competitive response of the other player. It was illustrated how the method could be applied by the telecommunication operator in the problem of choosing retail prices on local telecommunications services market, in prospect to necessity of negotiate conditions of interconnection agreement (wholesale decision) with the other player and to possible it's response on retail market.

Opis:
There are two definitions of the term Virtual Reality (VR) according to the VR pioneer, Jaron Lanier. The first definition refers to the visual programming technology (especially in computer games) which uses custom designed tools (like helmets, gloves and glasses) combined with special effects in order to achieve an illusion of physical space. The second meaning of the term VR encompasses all the elements of the „alternative” reality of cyberspace in which people communicate by means of different electronic devices. As such, VR allows those who participate in these interactions to manipulate and multiply their digital selves to such an extent as to loose their actual sense of self. VR technologies are used in a variety of professional capacities such as education, medicine, engineering, architecture and so on. Some negative consequences occur primarily with the overuse of VR for entertainment purposes (such as computer games) and include personality and behavioral changes in younger, adolescent users. There are also larger cultural influences to consider. The mind of a modern user of new technologies cannot keep up with the pace of societal changes, promoting behaviors which hinder communication, mutual understanding and cooperation. VR continues to affect the emotional, behavioral and sensory aspects of the psyche. The invasive persuasion of media and advertising influences people’s habits, opinions and ethics. One of the most disturbing cultural changes is the confusion of public and private spheres, Facebook friends for family and the substitution of cyberspace for home life.

game theory, dynamic games, equilibrium
Opis:
Although the title, ''Games and Dynamic Games"  of the new book by Alain Haurie, Jacek B. Krawczyk and Georges Zaccour suggests just another textbook on general game theory, with a little more stress made on dynamic aspect of games, the book appears to be something of novelty both in the scope and the treatment of the material. From the very first chapters of the book, it is clear that we will not be given another standard course of game theory, and that the dynamics of games will be the main issue. It starts with the simplest treatment of game dynamics, which is the extensive form of the game, and, having defined and explained the basic notions of static game theory, progresses to more complex dynamic models. Those start with deterministic repeated games, continue with variable state discrete time (or multistage) dynamic games and deterministic differential (that is, continuous time) games, and finish with stochastic models extending the ones presented before. Each part presents in a self-contained and comprehensive way, the main notions and solution concepts (such as open- and closed-loop strategies, Nash and correlated equilibria, subgame-perfectness, using threats to improve the performance of the equilibrium strategies) and theoretical results. It complements them with a number of economic applications, presented in detail. These applications relate to many fields of interest of economists, such as exploitation of renewable resources, environmental and energy issues, macroeconomics and finance. Each chapter ends with a set of excercices and a {\it game engineering} part, where a detailed presentation of a real-life application of some relevant game model is presented. Just this part is a novelty in the game-theoretic literature, as it shows to what extent the game-theoretic models can be applicable. Although the book presents the mathematical tools to model the situations of conflict in a rather rigorous way, it is clear that its target reader is someone with a background in economics or managemant science rather than mathematics. All the basic mathematical concepts used in the book are carefully explained, with those more complex ones (which appear in the latter chapters of the book) approached mainly through examples and intuitions. I believe this is a good decision of the authors, as in that way it makes the book really accessible to its potential readers. In fact, even though the tools (even those most advanced) of dynamic game theory have now been for many years used to model the economic interactions, surprisingly there has not been a single textbook addressed to more advanced students and researchers in economics and management science, presenting the state-of-art in the theory and applications of dynamic games in a comprehensive way. Those already existing required mathematical expertise well beyond what one could expect from typical economics/management students, and could not serve as textbooks for this type of readers. Moreover, those existing books concentrated without exception on some particular classes of dynamic games (such as differential games and their subclasses, stochastic games, repeated games). The book of Haurie, Krawczyk and Zaccour fills well the existing gap.Another important advantage of the book is its stress made not only on theoretical concepts and their adoption in real-life models, but on computation issues. The authors present a host of techniques to compute the solutions to the considered games either symbolically or numerically. They also provide information about software that can be used to solve similar games. Also the examples presented in game engineering sections are not abstract. They are based on real data, and issues of the credibility of the solutions obtained is discussed.The clarity of the exposition of often complicated topics is in general a big advantage of the book, although in latter chapters this clarity is sometimes unfortunatelly lost. The best example is the part about games over event trees with a confusing introduction concerning game with finite action sets and then the whole chapter concerning games with continuous ones. Also the last chapter, about stochastic-diffusion games, seems not very well conceived, as it jumps forth and back between an example and some more general considerations, leaving the reader confused about the generality of what is presented. These are certainly minor problems, but unfortunatelly there are other, more upseting issues. In general, it seems that the manuscript was not proofread carefully enough. The number of typos is enormous (the errata added to the book enumerates just a small fraction). Also some other faults, such as references to the colors on one of the figures, which is in black and white (p. 187), self-contradicting sentences like ''We use $\beta$ for a discount factor because we use $\beta$ to denote a strategy'' (p. 233), faults in references between chapters of the book (p. 372, footnote on p. 419) could have been easily eliminated if the book was properly proofread. What is worse though, is that there are also some more serious mistakes: one of the assumptions of the Kakutani fixed point theorem is missing, $\epsilon$-Nash equilibrium in Lemma 10.1 should be $A\epsilon$-equilibrium. And finally---it seems that most of the section 11.6.1 is missing from the manuscript. This significantly reduces the value of the book. Nevertheless, although I believe that all these errors should make the reader more cautious when reading the book, they do not unmake its main quality, which is acquainting all those interested in describing some real-life multi-agent economic situations in a rigorous way with the theory which provides the tools for doing it.

Opis:
We consider on-line Ramsey numbers defined by a game played between two players, Builder and Painter. In each round Builder draws an the edge and Painter colors it either red or blue, as it appears. Builder’s goal is to force Painter to create a monochromatic copy of a fixed graph H in as few rounds as possible. The minimum number of rounds (assuming both players play perfectly) is the on-line Ramsey number (H) of the graph H. An asymmetric version of the on-line Ramsey numbers r(G,H) is defined accordingly. In 2005, Kurek and Ruciński computed r(C3). In this paper, we compute r(C4,Ck) for 3 ≤k ≤ 7. Most of the results are based on computer algorithms but we obtain the exact value r(C4) and do so without the help of computer algorithms.

A different perspective from the more “traditional” approaches to studying solutions of games in partition function form has been presented. We provide a decomposition of the space of such games under the action of the symmetric group, for the cases with three and four players. In particular, we identify all the irreducible subspaces that are relevant to the study of linear symmetric solutions. We then use such a decomposition to derive a characterization of the class of linear and symmetric solutions, as well as of the class of linear, symmetric and efficient solutions.

Opis:
For a long time football, despite being a very important part of modern world, and because of it an important part of the socio-economic sphere, has not been the subject of scientific considerations. Economists have been interested in new problems, including football, since L.C. Robbins proposed a definition of economics and G.S. Becker started his economic approach. Furthermore, the development of economic instruments helpsthose changes. The main purpose of this paper is to show the usefulness of economic methods and instruments in finding solutions of various problems. Therefore, we choose and describe a part of scientific, football research. At the beginning, we try to answer two questions. Why has not football been the subject of scientific consideration? Do football clubs differ from other firms? The second question is vital for businessmen. We present the most important, economic characteristics of a football club, for example: a diversity of sports clubs targets and the lack of incentives to monopolize markets. We argue that only a sum of all mentioned characteristics makes a football clubs managment special. In the next part, we present and try to assess different propositions which should make football matches more attractive. We find three groups of features, which should grow the demand for football matches. In the first group there are principles during a match. The second group is connected with the league system, and the last one refers to organizing big, football tournaments. The application of economic instruments gives arguments for and against various propositions. The most important results suggest that if only one type of fouls is punished, it does not improve the flow of the game. Furthermore, the results show that the effect of the rule of three points for a win on the game is ambiguous. It can improve the attractiveness of a match, but it also grows the number of fouls. Next, we discuss the effectiveness of football clubs and coaches. First of all, we try to find whether positions in the football leagues after a season match to clubs classifications of effectiveness well. For this purpose, we present the results of effectiveness research which use data set from Spanish leagues. The results differ from each other, thus we do not get a clear answer. In the next step, we show research about coach effectiveness which suggests that coaches should not be judged solely on the basis of a number of won matches.In the last part, we argue, that the use of the data set from football matches allows for empirical verification of the economic instruments and methods, on the one hand. On the other hand, it helps to solve many problems related to football. However, not all situations related to football are suitable for scientific research. Part of them are too complex.

Opis:
One day, Jean-Jacques Rousseau, who was known mainly as a philosopher and a pedagogue, told a deer hunting story. In doing so, he managed to play a small role in the development of the branch of maths called ‘game theory’. Later his story was converted into a game. Initially game theory was used to explain exchange in the field of economics. Over time, the mathematical modeling was found to be useful in the social sciences. A game theory describes diverse and cognizant participants forced to make decisions. In regards to the game based on cooperation, a choice is at the same time a dilemma. It can be viewed as a moral or philosophical predicament and in addition it gives as an inside into the human psyche and behaviour. Game theory has the potential to offer an attractive mathematical model, useful in analyzing social interactions. Though currently unappreciated by pedagogy, it has the potential to be successfully used in pedagogical studies analyzing conflict of interest of all participants in an educational process.
