Further by using the Lusternik-Schnirelman category we will prove the existence of at least cat(Ω)+1 number of solutions. Key Words and Phrases: Nehari manifold, Lusternik-Schnirelman category, singularity, multiplicity. 2010 Mathematics Subject Classification: 35J35, 35J60. Published on-line: February 1st, 2023.
