In this paper, we study the following anisotropic problem with singularity:− ∑ i = 1 N∂x i| ∂x iu |p i ( x ) − 2∂x iu = λ | u | q ( x ) − 2 u | x | s ( x )+ f ( x , u ) , x ∈ Ω ,u = 0 , x ∈ ∂ Ω ,where Ω ⊂ R Nis a bounded domain with smooth boundary. Using the critical point theory, we obtain the existence of weak solutions for the problem under suitable conditions. Copyright © 2015 John Wiley & Sons, Ltd.
