Multiple blowup of solutions for a semilinear heat equation II

The present paper is concerned with a Cauchy problem for a semilinear heat equationequation(P){ut=Δu+upin RN×(0,∞),u(x,0)=u0(x)⩾0in RN with p>1p>1 and u0∈L∞(RN)u0∈L∞(RN). We show that if p>N−2N−1N−4−2N−1 and N⩾11N⩾11, then for each positive integer n⩾2n⩾2 there exist Ti>0Ti>0, i=1,2,…,ni=1,2,…,n, with T1
