R. Landes et V. Mustonen, ON PARABOLIC INITIAL-BOUNDARY VALUE-PROBLEMS WITH CRITICAL GROWTH FORTHE GRADIENT, Annales de l Institut Henri Poincare. Analyse non lineaire, 11(2), 1994, pp. 135-158
We prove the existence of weak solutions for the initial-boundary valu
e problem of the quasilinear parabolic equation partial derivative u/p
artial derivative t + A(u) + g(x, t, u, Du) = f Here A is a Leray-Lion
s type operator from V = L(P) (0, T; W-0(1), W-0(p) (OMEGA)) to its du
al space V, g is a nonlinear term with critical growth with respect t
o Du satisfying a sign condition and no growth condition with respect
to u; f is a given element in V.
