By means of suitable energy estimates and De Giorgi’s iteration technique we establish results asserting the global boundedness of appropriately defined weak solutions of these problems. We also show that a maximum principle holds for such equations.Online-Ressource (PDF-Datei: 18 S., 0,29 MB)enghttp://rightsstatements.org/vocab/InC/1.0/510Book
