On a mixed problem for a linear coupled system with variable coefficients
Electronic journal of differential equations, Tome 1998 (1998)
We prove existence, uniqueness and exponential decay of solutions to the mixed problem

$u''(x,t)-\mu(t)\Delta u(x,t)+\sum_{i=1}^n {\partial \theta\over\partial x_i}(x,t)=0 $

Classification : 35F15, 35N10, 35B40
