Existence of Positive Periodic Solutions of Fourth-order Singular p-Laplacian Neutral Functional Differential Equations

Fanchao Kong, Shiping Lu


Thisworkdealswiththeexistenceofpositiveperiodicsolutionsforthefourth-orderp-Laplacian neutral functional differential equations with a time-varying delay and a singularity. The results are
established using the continuation theorem of coincidence degree theory and some analysis methods. A numerical example is presented to illustrate the effectiveness and feasibility of the proposed criterion.
