Upper and lower absolutely continuous functions with applications to discontinuous differential equations

Krzysztof Topolski

Abstract

We use upper and lower absolutely continuous functions as subsolutions and supersolutions to discontinuous ordinary differential equations. We present sufficient conditions for the existence of extremal solutions to initial value problems. Due to a new notion of sub and supersolutions we generalize previous results and present elementary and relatively simple proofs.
