Uniqueness of renormalized solutions of degenerate elliptic-parabolic problems Carrillo Menéndez, José Wittbold, Petra 517.9 Equations of mixed type Degenerate elliptic equations Degenerate parabolic equations Ecuaciones diferenciales 1202.07 Ecuaciones en Diferencias We consider a general class of degenerate elliptic-paraboic problems associated with the equation b(v)(t) = div a(v, Dv) + f. Using Kruzhkov's method of doubling variables both in space and time we prove uniqueness and a comparison principle in L-1 for renormalized solutions DGICYT Depto. de Análisis Matemático y Matemática Aplicada Fac. de Ciencias Matemáticas TRUE pub 2023-06-20T16:53:27Z 2023-06-20T16:53:27Z 1999-07 journal article https://hdl.handle.net/20.500.14352/57344 0022-0396 10.1006/jdeq.1998.3597 eng PB93-0434 restricted access application/pdf Elsevier
