We continue the investigation of the solvability of boundary value problems for functional diﬀerential equations started in works by v and its pupils . The method is a development of the method applied by , ulashvili. To attain such a goal, we reduce the boundary value problem to a singular system of coupled nonlinear Fredholm integral equations, then we analyze its solvability through the existence of fixed points for the related operators. This system of integral equations is studied by means of Leray-Schauder’s topological degree theory. Full article.

In this paper, we study the following boundary value problem for second-order nonlinear difference equation where, an integer, and is continuous, scalar-valued function. We note that when, BVP() becomes the following BVP: which is called Neumann boundary value problem of difference equation and is a special case of BVP().Author: Jianye Xia, Yuji Liu. In this paper, we study the incompressible Navier-Stokes equations on a moving domain in \$\mathbb{R}^{3}\$ of finite depth, bounded above by the free surface and bounded below by a solid flat bottom. We prove that there exists a unique, global-in-time solution to the problem provided that the initial velocity field and the initial profile of the boundary are sufficiently small in Sobolev by:

• The unique solvability of ISPs are proved. The scattering data of the considered inverse scattering problems (ISPs) are described completely. • Solving the associated initial value problem or initial-boundary value problem for the nonlinear evolution equations (NLEEs) is carried out step-by-step. Many important theoretical and applied problems lead to the need of solving non-linear boundary value problems (and related problems) for equations and systems of equations of elliptic type (see, for example, –).For such a class of problems the basic numerical methods are projection methods (projection-grid, variational-difference, finite element) and difference methods (see –).
