Multiple solutions for nonresonance impulsive functional differential equations

open access: yesElectronic Journal of Differential Equations, 2003
In this paper we investigate the existence of multiple solutions for first and second order impulsive functional differential equations with boundary conditions. Our main tool is the Leggett and Williams fixed point theorem.

Existence of Positive Solutions for m-Point Boundary Value Problems on Time Scales

open access: yesDiscrete Dynamics in Nature and Society, 2009
We study the one-dimensional p-Laplacian m-point boundary value problem (φp(uΔ(t)))Δ+a(t)f(t,u(t))=0, t∈[0,1]T, u(0)=0, u(1)=∑i=1m−2aiu(ξi), where T is a time scale, φp(s)=|s|p−2s, p>1, some new results are obtained for the existence of at least one, two,

Existence and multiplicity of solutions of fractional differential equations on infinite intervals

open access: yesBoundary Value Problems
In this research, we investigate the existence and multiplicity of solutions for fractional differential equations on infinite intervals. By using monotone iteration, we identify two solutions, and the multiplicity of solutions is demonstrated by the ...

Existence of three non-negative solutions for a three-point boundary-value problem of nonlinear fractional differential equations

open access: yesElectronic Journal of Differential Equations, 2012
This article concerns the existence of three non-negative solutions for two kinds of three-point boundary-value problems of nonlinear fractional differential equations, where the fractional derivative is taken in the Riemann-Liouville sense.
