设p>1,Ω是RN中光滑有界区域.本文研究柯西-诺伊曼问题[公式:见文本]我们证明,如果u在t=T处爆炸,则[公式:见文本]在(P)中方程的柯西问题的某些条件下,某些C>0。特别地,如果(N-1)2 p <N(N+2),则(n)成立。
Let p>1 and Ω be a smoothly bounded domain in RN. This paper is concerned with a Cauchy–Neumann problem [Formula: see text] We show that if u blows up at t=T, then [Formula: see text] with some C>0 under some condition on the Cauchy problem for the equation in (P). In particular, (∗) holds if (N−1)2p<N(N+2).
