摘要
利用位势井方法,讨论了一类半线性双温度热传导方程,对其初边值问题整体弱解的存在性进行研究,给出了整体弱解的存在性定理,且证明了方程的解或解对x的某些导数的L2模估计式.
In this paper,by using potential well method,the existence of the global weak solutions for a class of semilinear dual-temperature equation is studied.The existence theorems of the global weak solu-tions,and some norm estimates of solutions and their derivatives are obtained.
