摘要
处理了一类更复杂的抛物方程组解的整体存在性和爆破性,方程组带有内吸收且非局部源项的系数是函数,这跟常系数的情形有本质的区别.在一定条件下,分别证明了解的全局爆破和爆破速率.
This paper deals with the global existence and blow up properties of solutions for a more com- plicate parabolic equations with weighted nonlocal sources and absorptions.This is essentially different from the situation of constant coefficients.Under certain conditions,the global blow up of solutions and the rates of blow up are shown respectively.
