Sunto
Si studiano alcune equazioni e disequazioni di tipo parabolico semilineare con termine non lineare discontinuo, in presenza di condizioni di vincolo anche non convesse. Per ottenere dei teoremi di esistenza si interpretano le soluzioni come «curve di massima pendenza rilassata» per un opportuno funzionale sul vincolo considerato.
