Nontrivial solutions of systems of Hammerstein integral equations with first derivative dependence

, 2017
By means of classical fixed point index, we prove new results on the existence, non-existence, localization and multiplicity of nontrivial solutions for systems of Hammerstein integral equations where the nonlinearities are allowed to depend on the first

Existence of solutions for integral boundary value problems of second-order ordinary differential equations

, 2012
In this paper, we investigate the existence of solutions for some second-order integral boundary value problems, by applying new fixed point theorems in Banach spaces with the lattice structure derived by Sun and Liu.MSC:34B15, 34B18, 47H11.
