Infinitely many solutions for systems of multi-point boundary value problems using variational methods

TL;DR: In this article, the existence of infinitely many classical solutions to the multi-point boundary value system was obtained based on critical point theory, and the analysis was based on the analysis of critical point theories.
Journal ArticleDOI

Periodic solutions of first order functional differential equations

TL;DR: Conditions for the existence of multiple (even infinitely many) T-periodic solutions of one of the problems are obtained.
Journal ArticleDOI

Symmetric positive solutions of nonlinear boundary value problems

TL;DR: In this paper, the existence of symmetric positive solutions of the nonlinear boundary value problem is studied and sufficient conditions are obtained for the problem to have one, any finite number, and a countably infinite number of such solutions.
Journal ArticleDOI

Infinitely Many Solutions for Systems of Sturm–Liouville Boundary Value Problems

TL;DR: In this article, the authors obtained the existence of infinitely many classical solutions to the boundary value system with Sturm-Liouville boundary conditions with the Ricceri variational principle and critical point theory.
Journal ArticleDOI

Necessary and sufficient conditions for the existence of symmetric positive solutions of singular boundary value problems

TL;DR: In this paper, necessary and sufficient conditions are obtained for the existence of symmetric positive solutions to the boundary value problem ( | u'| p − 1 u') = f ( t, u, u ', u'), t ∈ ( 0, 1 ), u ( 2 i ) ( 0 ) = u (2 i )( 1 ) = 0, i = 0, 1.
