Maximum principles for a family of nonlocal boundary value problems.
Multiple positive solutions for impulsive singular boundary value problems with integral boundary conditions.
Multiple positive solutions for -type semipositone conjugate boundary value problems of nonlinear fractional differential equations.
Multiple positive solutions for nonlinear boundary value problems with integral boundary conditions
In this paper we investigate the existence of multiple positive solutions for nonlinear boundary value problems with integral boundary conditions. We shall rely on the Leggett-Williams fixed point theorem.
Multiple positive solutions for nonlinear second-order m-point boundary-value problems with sign changing nonlinearities.
Multiple sign-changing solutions for sub-linear impulsive three-point boundary-value problems.
