The paper is concerned with the existence and multiplicity of positive solutions for a nonlinear m-point boundary value problem. The proofs are based on a fixed-point theorem and a fixed-point index theorem in cones.
This paper is concerned with positive solutions and the structure of eigenvalue regions for a two-delay singular differential system with a twin-parameter.
