摘要
It is known that for 1【p【+∞, n=2 or 1【p【(n+2)/(n-2), n≥3, the elliptic problemhas a unique solution (x) which is radially symmetric and satisfies ’(0)=0, ’(r)【0, (x)~Me<sup>-α|x|<sup>2</sup></sup> as |x|→∞. Let u(x, t) be the solution (positive) ofIn Ref. [1| it has been proved that if λ】1, then u(x, t) blows up in finite time. We de-
