Detalhes bibliográficos
Resumo:We show that a locally bounded nonnegative weak solution of a general double degenerate parabolic equation ut −diva(x,t,u,∇u) = b(x,t,u,∇u), satisfying specific structure conditions is locally continuous, generalizing therefore the study of the local regularity theory for the saturation in the flow of two immiscible fluids in a porous medium presented in DiBenedetto et al. [16].
