Journal ArticleDOI
Controllability of nonlinear neutral evolution integrodifferential systems
TL;DR: In this article, sufficient conditions for controllability of nonlinear neutral evolution integrodifferential systems in a Banach space are established by using the resolvent operators and the Schaefer fixed-point theorem.
Journal ArticleDOI
Multiplicity of solutions and source terms in a fourth order nonlinear elliptic equation
TL;DR: In this article, the authors investigated relations between multiplicity of solutions and source terms of the fourth order nonlinear elliptic boundary value problem under Dirichlet boundary condition Δ 2 u + c Δ u = bu + + f in Ω, where Ω is a bounded open set in R n with smooth boundary.
