On p‐Laplace Equations with Singular Nonlinearities and Critical Sobolev Exponent

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
In this paper, we deal with p‐Laplace equations with singular nonlinearities and critical Sobolev exponent. By using the Nehari manifold, Mountain Pass theorem, and Maximum principle theorem, we prove the existence of at least four distinct nontrivial solutions.
