摘要: In this paper, we are concerned with the Cauchy problem:
ut=△u+|u|γ-1u-u xRn,γ>1,tR+ u(x,0)=u0(x) in Dqα. We got some existence and asymptotic results of their global solutions. Additionally, we got the global existence theorem of the Cauchy problem
ut=△u+|u|γ-1u xRn,γ>1,tR+ u(x,0)=u0(x) in Dqα, where q∈[(1)/2n(γ-1),∞),α=(2)/γ-1-(n)/q, in the case(1)/2n(γ-1)>1.
