By means of variational method, we study a singular critical growth semilinear elliptic problem: -Δu = Q(x)|u|~(2~*-2)u + μu/|x|~2 + λμ, u ∈ H_0~1(Ω), where 2~* = 2N/N-2, N ≥ 7, 0 < μ < (N-2)~2/4, λ > 0, and Q(x) is a positive function on Q,. By investigating the effect of the coefficient of the critical nonlinearity, we prove the existence of sign-changing solutions.
