摘要

Let Ω⊂R~n (n = 2 or n = 3) be a bounded domain. We consider the thermistor system (1) ∇·J = 0, (2) (∂u)/(∂t)+∇·q = f(x,t,u,∇_φ) in Ω×] 0,T[, where (1) is a p-Laplace type equation for (u = temperature, φ = electrostatic potential). We prove the existence of a weak solution (φ,u) of (1)-(2) under mixed boundary conditions for φ, and a Robin boundary condition and an initial condition for u.
