On the existence of periodic solutions in the thermistor problem with degenerate thermal conductivity

Abstract

This paper deals with the existence of weak periodic solutions for a parabolic-elliptic system proposed as a model for a time dependent thermistor with degenerate thermal conductivity. Applying the maximal monotone mappings theory, we prove an existence result for weak periodic solutions.
