Electronic Journal of Differential Equations, Conference 08 (2002), pp. 121-131 Title: A note on $W^{1,p}$ estimates for quasilinear parabolic equations Authors: Ireneo Peral (U.A.M., Madrid, Spain) Fernando Soria (U.A.M., Madrid, Spain) Abstract: This work deals with the study of the $W^{1,p}$ regularity for the solutions to parabolic equations in divergence form. An argument by perturbation based in real analysis is used. Published October 21, 2002. Math Subject Classifications: 35K10, 35K55, 42B25.
