Positive Solutions of the Semipositone Neumann Boundary Value Problem
Mathematical Modelling and Analysis, 2015 In this paper we consider the Neumann boundary value problem at resonance −u''(t) = f t, u(t) , 0 < t < 1, u' (0) = u' (1) = 0. We assume that the nonlinear term satisfies the inequality f(t, z) + α2z + β(t) ≥ 0, t ∈ [0, 1], z ≥ 0, where β : [0, 1]

On a Neumann boundary value problem for Ermakov–Painlevé III [PDF]
Electronic Journal of Qualitative Theory of Differential Equations, 2019 A Neumann-type boundary value problem is investigated for a hybrid Ermakov–Painlevé equation. Existence properties are established and a sequence of approximate solutions is investigated.

A Neumann boundary-value problem on an unbounded interval [PDF]
Electronic Journal of Differential Equations, 2008 We study a Neumann boundary-value problem on the half line for a second order equation, in which the nonlinearity depends on the (unknown) Dirichlet boundary data of the solution. An existence result is obtained by an adapted version of the method of

HARMONIC INTERPOLATING WAVELETS IN NEUMANN BOUNDARY VALUE PROBLEM IN A CIRCLE [PDF]
Ural Mathematical Journal, 2019 The Neumann boundary value problem (BVP) in a unit circle is discussed. For the solution of the Neumann BVP, we built a method employing series representation of given \(2 \pi\)-periodic continuous boundary function by interpolating wavelets consisting ...

On solutions of neumann boundary value problem for the liénard type equation [PDF]
Mathematical Modelling and Analysis, 2008 We provide conditions on the functions f(x) and g(x), which ensure the existence of solutions to the Neumann boundary value problem for the equation x'' + f(x)x'2+g(x)=0.

Existence and uniqueness of solutions for a Neumann boundary-value problem
Electronic Journal of Differential Equations, 2011 In this article, we show the existence and uniqueness of positive solutions for perturbed Neumann boundary-value problems of second-order differential equations. We use a fixed point theorem for general $alpha$-concave operators.

Solutions to nonlocal Neumann boundary value problems
Electronic Journal of Qualitative Theory of Differential Equations, 2018 In this paper we study the nonlocal Neumann boundary value problem of the following form $$ u'' =f(t,u,u'),\quad u'(0)=0, \quad u'(1)=\int_{0 }^{1}u'(s)dg(s), $$ where $f:[0,1]\times\mathbb R^n\times\mathbb R^n\to\mathbb R^n$ and $g=\mbox{diag}(g_1 ...

On One Initial Boundary Value Problem for the Burgers Equation in a Rectangular Domain [PDF]
Қарағанды университетінің хабаршысы. Математика сериясы, 2021 We consider some initial boundary value problems for the Burgers equation in a rectangular domain, which in a sense can be taken as a model one. The fact is that such a problem often arises when studying the Burgers equation in domains with moving ...
