Abstract:

In this paper, we are concerned with the following elliptic equation involving critical Sobolev-Hardy exponent
u-μ(u)/(|x|2)+λa(x)uq=(|u|2*(s)-2)/(|x|s)u,x∈RN,(0.1)
u>0,uD1,2(RN),
where 2*(s)=(2(N-s))/(N-2) is the critical Sobolev-Hardy exponent, N ≥ 3, λ∈R, 0 ≤ s < 2, 1 < q < 2*-1, 0 ≤ μ < μ=((N-2)2)/(4), a(x)∈C(RN). We firstly use an abstract perturbation method in critical point theory to obtain the existence results of positive solutions of the equation for small value of|λ|. Secondly, we focus on an anisotropic elliptic equation of the form 
-div[(1+λb(x))▽u]+λa(x)uq=μ(u)/(|x|2)+(|u|2*(s)-2)/(|x|s)u,x∈RN,(0.2)
u>0,uD1,2(RN),
The same abstract method is used to yield existence result of positive solutions of the equation for small value of |λ|.
