Abstract: This article is contributed to the Cauchy problem

{\Dut=Δu+K(|x|)up  in Rn×(0,T),u(x,0)=φ(x)  in Rn;

with initial function φ0. The stability of positive radial steady state, which are positive solutions of △u+K( | x|)up=0, is obtained when p is critical for general K(|x|).

Key words: Stability, Cauchy problem, asymptotic stability
