Using Kruzhkov's method of doubling variables both in space and time we prove uniqueness and a comparison principle in L-1 for renormalized solutionsengjournal articlehttp://www.sciencedirect.com/science/article/pii/S0022039698935975http://www.sciencedirect.com/restricted access517.9Equations of mixed typeDegenerate elliptic equationsDegenerate parabolic equationsEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
