Positive solutions of nonlocal boundary value problems involving integral conditions [PDF]
Nonlinear Differential Equations and Applications NoDEA, 2008 We establish the existence of multiple positive solutions of nonlinear equations of the form $$-u^{\prime\prime}(t) = g(t)f(t, u(t)), t \in (0, 1),$$ where g, f are non-negative functions, subject to various nonlocal boundary conditions. The common feature is that each can be written as an integral equation, in the space C[0, 1], of the form

Electronic Journal of Qualitative Theory of Differential Equations, 2011 This paper studies a nonlinear fractional differential equation of an arbitrary order with four-point nonlocal integral boundary conditions. Some existence results are obtained by applying standard fixed point theorems and Leray-Schauder degree theory ...

New Existence Results for Fractional Integrodifferential Equations with Nonlocal Integral Boundary Conditions [PDF]
Abstract and Applied Analysis, 2015 We consider a boundary value problem of fractional integrodifferential equations with new nonlocal integral boundary conditions of the form:x(0)=βx(θ), x(ξ)=α∫η1x(s)ds, and0<θ<ξ<η<1. According to these conditions, the value of the unknown function at the left end pointt=0is proportional to its value at a nonlocal pointθwhile the value at ...
