On fourth order retarded equations with functional boundary conditions: a unified approach
arXiv:2209.04619 · doi:10.3934/dcdss.2023006
Abstract
By means of a recent Birkhoff-Kellogg type theorem, we discuss the solvability of a fairly general class of parameter-dependent fourth order retarded differential equations subject to functional boundary conditions. We seek solutions within a translate cone of nonnegative functions. We provide an example to illustrate our theoretical results.
