Existence of weak solutions for the nonstationary problem of the Joule heating of a conductor. (English) Zbl 0769.35059

The author considers an initial-boundary value problem for a system of two nonlinear partial differential equations using the Faedo-Galerkin method. The problem describes the electric heating of a conducting body. The main result is a theorem of existence of weak solutions for an arbitrarily large interval of time.
