Opis:: Under additional conditions uniqueness of the solution is proved for the following problem. Given 1) the spectrum of the Dirichlet problem for the Sturm-Liouville equation on [0, a] with real potential q(x) mem L2(0, a), 2) a certain part of the spectrum of the Dirichlet problem for the same equation on [a/3, a] and 3) the potential on [0, a/3]. The aim is to find the potential on [a/3 ,a].

Lagrange problem
lower closure theorem
Opis:: In the paper, the Lagrange problem given by a fractional boundary problem with partial derivatives is considered. The main result is the existence of optimal solutions based on the convexity assumption of a certain set. The proof is based on the lower closure theorem and the appropriate implicit measurable function theorem.

Tytuł:: Hamiltonian trajectories and saddle points in mathematical economics
Autorzy:: Rockafellar, R. T.
Powiązania:: https://bibliotekanauki.pl/articles/970735.pdf
Data publikacji:: 2009
Wydawca:: Polska Akademia Nauk. Instytut Badań Systemowych PAN
Tematy:: infinite horizon optimal control
convex Lagrange problems
Hamiltonian saddle points
overtaking criteria
Ramsey's problem
economic growth
Opis:: Infinite-horizon problems of kinds that arise in macroeconomic applications present a challenge in optimal control which has only partially been met. Results from the theory of convex problems of Lagrange can be utilized, to some extent, the most interesting feature being that in these problems the analysis revolves about a rest point of the Hamiltonian, which is at the same time a saddle point of the Hamiltonian in the minimax sense. The prospect is that in this situation the Hamiltonian dynamical system exhibits saddle point behavior in the differential equation sense as well. Some results are provided in this direction and coordinated with notions of asymptotic optimization, which mathematical economists have worked with.

Tytuł:: Average case analysis of the set packing problem
Autorzy:: Szkatuła, K.
Powiązania:: https://bibliotekanauki.pl/articles/206822.pdf
Data publikacji:: 2014
Wydawca:: Polska Akademia Nauk. Instytut Badań Systemowych PAN
Tematy:: Lagrange
set packing problem
Opis:: The paper deals with the well known set packing problem and its special case, when the number of subsets is maximized. It is assumed that some of the problem coefficients are realizations of mutually independent random variables. Average case (i.e. asymptotical probabilistic) properties of selected problem characteristics are investigated for the variety of possible instances of the problem.
