Abstract:

This note is a continuation of the work[17]. We study the following quasilinear elliptic equations
-△pu-(μ)/(|x|p)|u|p-2u=Q(x)|u|(Np)/(N-p)-2u, x∈RN,
where 1 < p < N, 0≤μ < ((N-p)/p)p and QL(RN). Optimal asymptotic estimates on the gradient of solutions are obtained both at the origin and at the infinity.

Key words: quasilinear elliptic equations, Hardy's inequality, gradient estimate
