We consider the following problem with the critical exponent p1=r ut=d1Δua1u+upvq+δ1(x,t),xΩ,t>0,vt=d2Δva2v+urvs+δ2(x,t),xΩ,t>0,uη=vη=0,xΩ,t>0,u(x,0)=u0(x),v(x,0)=v0(x),xΩ.Here q,r,d1,d2,a1 and a2 are positive constants, p>1, s>1, δ1, δ2, u0 and v0 are nonnegative smooth functions, ΩRd(d1) is a bounded smooth domain. Whether d1d2 or d1=d2, we establish the results on the finite-time blowup and global existence of the solution, which improves those of Theorem 1.2 in Li et al. (2017).
