By means of the continuation method for contractions we prove the existence of solutions of Dirichlet boundary value problems in convex sets. As an application we prove the existence of concave solutions of certain boundary value problems in ordered Banach spaces.

Opis:
In this paper, we study nonlinear second order differential inclusions with a multivalued maximal monotone term and nonlinear boundary conditions. We prove existence theorems for both the convex and nonconvex problems, when $domA ≠ ℝ^{N}$ and $domA = ℝ^{N}$, with A being the maximal monotone term. Our formulation incorporates as special cases the Dirichlet, Neumann and periodic problems. Our tools come from multivalued analysis and the theory of nonlinear monotone operators.

Opis:
The following book deals with various boundary value problems for differential equations. As Juliusz Schauder, one of the pioneers and unsurpassed masters (at least for the author), used to say, the most important thing is to know the methods, not the theorems. Thus, we are interested in a set of methods of Nonlinear Analysis applied to such boundary value problems. Since we want to avoid the difficulties associated with partial equations (already the theory of linear partial differential equations requires the use of subtle concepts and tools of Functional Analysis), we choose examples showing applications of the above-mentioned methods among ordinary differential equations. We are interested in nonlinear equations, but the boundary conditions we discuss are usually linear. By boundary conditions, we mean here any additional equations that the solutions of the differential equation are expected to satisfy. Such additional conditions are necessary if we want to have one (or more) solutions - after all, a given differential equation has infinitely many solutions. These additional conditions may be initial conditions, conditions to be satisfied by the function at the extremes of the domain (boundary conditions), but they may also be multipoint or, more broadly, nonlocal e.g. when there is an integral of the solution in the equation. On the other hand, the wealth of methods of nonlinear analysis is so great that we emphasize a certain set of methods (mainly topological) preferred by the author. The examples on which we present applications of these methods are in majority taken from the work of the research team that consists of the author and his former PhD students. Thus, this survey is not a monograph of the subject in a strict sense, which is reflected in the first word of the title "Selected".

positive solution
Opis:
An application is made of a new Avery et al. fixed point theorem of compression and expansion functional type in the spirit of the original fixed point work of Leggett and Williams, to obtain positive solutions of the second order right focal discrete boundary value problem. In the application of the fixed point theorem, neither the entire lower nor entire upper boundary is required to be mapped inward or outward. A nontrivial example is also provided.
