Remarks on nonlocal boundary value problems at resonance

Applied Mathematics and Computation, 2010
The author considers the nonlocal boundary value problems \[ -u''(t)=f(t, u(t), u'(t)),\quad u(0)=0,\;u(1)=\int^1_0 tdA(t), \] and \[ -(p(t)u')'(t)=f(t, u(t),\;u'(t)),\quad u'(0)=0,\;u(1)=\int^1_0 tdB(t). \] He shows that it is important to allow the nonlinear term \(f\) to change sign when discussing the existence of positive solutions by providing ...

Nonlocal boundary-value problems with a shift

Mathematical Notes of the Academy of Sciences of the USSR, 1985
This first part of the paper deals with strongly elliptic differential- difference equations; it is an extract of an earlier paper [J. Differ. Equations 63, 332-361 (1986; Zbl 0598.35122)]. The second part applies the results of the first part to linear elliptic boundary value problems of second order. In a domain \(D=(0,d)\times G\subset {\mathbb{R}}^

Singular nonlocal boundary value problems

Nonlinear Analysis: Theory, Methods & Applications, 2005
Abstract This paper presents conditions for the existence of solutions to the differential equation ( g ( x ′ ) ) ′ = f ( t , x , x ′ ) satisfying the nonlocal boundary conditions min { x ( t ) : 0 ⩽ t ⩽ T } = 0 and Φ ( x ′ ) = 0 .

The Solvability of a Nonlocal Boundary Value Problem

Mathematica Slovaca, 2015
Abstract In this paper we consider the following boundary value problem where f : [0, 1]×ℝk×ℝk → ℝk and the integral is meant in the sense of Riemann- Stieltjes. We give conditions for

BOUNDARY VALUE PROBLEMS WITH STRONG NONLOCALNESS FOR ELLIPTIC EQUATIONS

Mathematics of the USSR-Izvestiya, 1990
The author constructs the Noether theory for a class of strongly nonlocal elliptic boundary value problems. Let \(\Omega\) be a bounded domain in \(\mathbb{R}^{n+1}\) with smooth boundary \(X\), and let \(P\) be an \(m\)th-order elliptic operator in \(\Omega\) with smooth coefficients.
