Existence of solutions for functional boundary value problems of second-order nonlinear differential equations system at resonance

open access: yesAdvances in Difference Equations, 2017
In this paper, by using the coincidence degree theory due to Mawhin and constructing suitable operators, we study the solvability for functional boundary value problems of second-order nonlinear differential equations system at resonance with dim Ker L =

Positive Solutions for Systems of Quasilinear Equations with Non-homogeneous Operators and Weights

open access: yesAdvanced Nonlinear Studies, 2020
In this paper we deal with positive radially symmetric solutions for a boundary value problem containing a strongly nonlinear operator. The proof of existence of positive solutions that we give uses the blow-up method as a main ingredient for the search ...
