摘要
讨论牛曼边界条件下具有常数收获率的竞争—扩散问题解的性态,得到当收获率满足当条件时,种群u将在有限时刻被消灭。
In this paper the behavior of the solution of a competition-diffusion problem with constant harvesting rate under neumann boundary, condition has been discussed. Particularly, it has been obtained that species u should be wiped out at finite time if harvesting rate satisfies suitable condition.
