。考虑具有非负初值的合作反应扩散系统的柯西问题。在这里,我们讨论了仅在fi空间中发生的解的爆破问题。我们给出了这类现象存在的充分条件,并研究了解在爆破时在空间fi正定性中的渐近行为。一般情况下,关于半线性抛物型方程组的爆破点位置的证明相对较少。然而,对于某一类初值问题,我们的结果也适用于一大类非线性问题。这是因为,当爆破只发生在fi空间时,反应的反应比扩散的反应强得多,并且fi空间的行为可以用解的fl很好地逼近。
. We consider the Cauchy problem of cooperative reaction-di¤usion systems with nonnegative initial data. Here we discuss the blow-up of a solution that occurs only at space infinity. We give su‰cient conditions for such phenomena, and study an asymptotic behaviour at space infinity of the solutions at the blow-up time. In general, relatively little is proved on the locations of blow-up point for semilinear parabolic systems. However, our results can be applied to a large class of nonlinearity for some class of initial value. The reason of this is that, when the blow-up occurs only at space infinity, the e¤ect of reaction is much stronger than that of di¤usion, and the behaviour at space infinity is well approximated by the flat solution.
