Hölder estimates for nonlinear degenerate parabolic sytems.
Continuity for bounded solutions of multiphase Stefan problem
We establish the continuity of bounded local solutions of the equation . Here is any coercive maximal monotone graph in , bounded for bounded values of its argument. The multiphase Stefan problem and the Buckley-Leverett model of two immiscible fluids in a porous medium give rise to such singular equations.
