Existence and nonexistence of positive solutions for the second-order m-point eigenvalue impulsive boundary value problem [PDF]

, 1995
This paper is devoted to the study of the existence and nonexistence of positive solu-tions for a second-order m-point eigenvalue impulsive boundary value problem. We use the fixed point theorems on the cones in order to achieve our results.

Uniqueness Results for Positive Solutions of Ψ–Caputo Fractional Differential Equations

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
This paper establishes rigorous existence and uniqueness results for positive solutions of boundary value problems involving the Ψ–Caputo fractional operator. The equations combine continuous nonlinear terms with Riemann–Liouville fractional integrals and are subject to newly formulated integral boundary conditions.

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

, 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 ...
