The Debye system: Existence and large time behavior of solutions.
(English)
[J] Nonlinear Anal., Theory Methods Appl. 23, No.9, 1189-1209 (1994). ISSN 0362-546X

The authors study the so-called Debye system: $$u\sb t = \nabla \cdot (\nabla u - u \nabla \varphi), \quad v\sb t = \nabla \cdot (\nabla v + v \nabla \varphi)$$ (coupled through $\varphi$ satisfying $\Delta \varphi = u - v)$ in a bounded domain $\Omega \subset \bbfR\sp n$ with smooth boundary and no flux boundary conditions. Conditions for local and global existence and uniqueness of weak solutions are given in several space dimensions $n$. For $n = 2,3$ it is shown that a weak solution of the system above converges to the (unique) stationary solution if $t\to\infty$.
