Abstract
In this paper, we establish the existence of multiple solutions for p-Laplacian problems involving critical exponents and singular cylindrical potential, by using Ekeland’s variational principle and mountain pass theorem without Palais-Smale conditions.

The aim of this paper is to establish the existence and multiplicity of solutions to the following quasilinear elliptic problem ( ) λ,μ −∆ pu−= μ y − p u p−2 u u ∈ 1p ( N ), h ( y) y −s u q−2 u + λ g ( x) in N, y ≠ 0( ) Where ∆ pu= div ∇u p−2 ∇u,1< p < k, k and N are integers with N>p, p ≤ k N, =N × N

Summary
The aim of this paper is to establish the existence and multiplicity of solutions to the following quasilinear elliptic problem ( ) λ,μ. ( ) The problem λ,μ has been studied by Bouchekif and Matallah in [2], by using Ekeland.s variational principle and mountain pass theorem, they established the existence of two nontrivial solutions when 0 < μ ≤ μN , λ ∈(0, Λ∗ ), where Λ∗ is a positive constant and under sufficient conditions on functions g and h. In [11], Xuan studied the multiple weak solutions for p-Laplace equation with singularity and cylindrical symmetry in bounded domains. They only considered the equation with sole critical Hardy-Sobolev term. We start by recalling the following definition and properties from the paper [6]
