Heteroclinic and homoclinic solutions for nonlinear second-order coupled systems with phi-Laplacians
Robert de Sousa, Feliz Minhós
In this paper we present sufficient conditions for the existence of heteroclinic or homoclinic solutions for second order coupled systems of differential equations on the real line…
Existence and multiplicity results for some generalized Hammerstein equations with a parameter
Lucía López-Somoza, Feliz Minhós
This paper considers the existence and multiplicity of fixed points for the integral operator \begin{equation*} {\mathcal{T}}u(t)=λ\,\int_{0}^{T}k(t,s)\,f(s,u(s),u^{\prime }(s),\do…
On multi-point resonant problems on the half-line
Lucía López-Somoza, Feliz Minhós
In this work we obtain sufficient conditions for the existence of bounded solutions of a resonant multi-point second-order boundary value problem, with a fully differential equatio…
Existence result for impulsive coupled systems on the half-line
Feliz Minhós, Robert de Sousa
This work considers a second order impulsive coupled system of differential equations with generalized jump conditions in half-line, which can depend on the impulses of the unknown…
