Multiplicity of solutions for discrete 2n-th order periodic boundary value problem

Multiplicity of Solutions for Discrete 2n-TH Order Periodic Boundary Value Problem with φp-Laplacian

“…From the point of view of orders for equations, the earliest outstanding work comes from the research team of Yu and Zhou [9]. In recent years, our group has also done further generalization and expansion without the p-Laplacian; our methods have mainly included the topological degree theory and fixed point theorem, see [10,11].…”

“…Refs. [10][11][12][13] is a recent work on this topic that the reader should consult. For instance, the following issue was researched by the authors in [12],…”
