Neumann boundary value problems across resonance [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2006 The authors consider the Neumann boundary value problem to the second order differential equation \[ -x''(t)-\alpha(t)x'(t)=f(t, x(t)), \] \[ x'(0)=A,\quad x'(\pi)=B, \] where \(\alpha(t)\) is a continuous function and \(0\leq f_x(t, x)\leq \beta\), \(\beta\in L^{\infty}[0, \pi]\).

The Initial and Neumann Boundary Value Problem for a Class Parabolic Monge-Ampère Equation [PDF]
Abstract and Applied Analysis, 2013 We consider the existence, uniqueness, and asymptotic behavior of a classical solution to the initial and Neumann boundary value problem for a class nonlinear parabolic equation of Monge-Ampère type. We show that such solution exists for all times and is

A Source Problem for the Helmholtz Equation via a Dirichlet-to-Neumann Map
Abstract and Applied Analysis, 2021 In this paper, we consider a source problem for a time harmonic acoustic wave in two-dimensional space. Based on the boundary integral equation method, a Dirichlet-to-Neumann map in terms of boundary integral operators on the boundary of the source is ...

Solution of the mixed boundary problem for the Poisson equation on two-dimensional irregular domains
Informatika, 2023 Objectives. A finite-difference computational algorithm is proposed for solving a mixed boundary-value problem for the Poisson equation given in two-dimensional irregular domains.Methods. To solve the problem, generalized curvilinear coordinates are used.

A Neumann boundary value problem for a class of gradient systems [PDF]
Opuscula Mathematica, 2014 In this paper we study a class of two-point boundary value systems. Using very recent critical points theorems, we establish the existence of one non-trivial solution and infinitely many solutions of this problem, respectively.

TWO-DIMENSIONAL HYBRIDS WITH MIXED BOUNDARY VALUE PROBLEMS
Acta Polytechnica, 2016 Boundary value problems are considered on a simplex F in the real Euclidean space R2. The recent discovery of new families of special functions, orthogonal on F, makes it possible to consider not only the Dirichlet or Neumann boundary value problems on F,
