讨论了一类由两个热方程所组成的串联系统,在该串联系统中,将第一个方程的解作为第二个方程的边界输入,建立了解的边界Carleman型先验估计,即解在区域内部的加权L2模可以被解在部分边界上的加权L2模控制.
This paper is concerned with a class of cascade system composed by two heat equations.In this cascade system,the solution of the first equation is the boundary input of the second equation.The boundary Carleman-type priori estimates of solutions are established.That is,the weighted L2 norm of a solution in the domain is controlled by the weighted L2 norm of a solution on the partial boundary.
