AbstractExistence results to boundary value problems for non-potential p, q-Laplacian systems with potential boundary conditions are established. The approach relies on Schaefer…
Abstract We study the existence of nontrivial solutions to the boundary value problem -u^{\prime \prime}+cu\prime+\lambda u =f(x,u),\ \ -\infty<x<+\infty…
AbstractExistence, localization and multiplicity results of positive solutions to a system of singular second-order differential equations are established by means…
Abstract In this work, existence and localization results for C_1-solutions to elliptic Dirichlet boundary value problems are established. The approach…
