Solution of a two-dimensional stationary induction heating problem without boundedness of the coefficients. (English) Zbl 0894.35035
Authors’ summary: We consider a system of equations modelling a quasistationary induction heating process. Existence of a solution is obtained in Sobolev spaces using estimations in $$L^\infty$$-norm. Using a truncation technique, we build a sequence of truncated problems, the solutions of which converge to a solution of the initial unbounded coefficient problems.
