Existence of multiple positive solutions for p-Laplacian multipoint boundary value problems on time scales

Advances in Differential Equations, 2013
In this paper, we consider p-Laplacian multipoint boundary value problems on time scales. By using a generalization of the Leggett-Williams fixed point theorem due to Bai and Ge, we prove that a boundary value problem has at least three positive ...

On singularly weighted generalized Laplacian systems and their applications

Advances in Nonlinear Analysis, 2018
We study the homogeneous Dirichlet boundary value problem of generalized Laplacian systems with a singular weight which may not be integrable. Some explicit intervals which correspond to the existence and nonexistence of positive solutions for the system

Existence of positive periodic solutions of second-order differential equations with weak singularities

Boundary Value Problems, 2014
We establish the existence of positive periodic solutions of the second-order differential equation x″+a(t)x=f(t,x)+c(t) via Schauder’s fixed point theorem, where a∈L1(R/TZ;R+), c∈L1(R/TZ;R), f is a Caratheodory function and it is singular at x=0.
