In this paper we deal with the Cauchy problem associated to a class of quasilinear singular parabolic equations with L-infinity coefficients, whose prototypes are the p-Laplacian (2N/N+1 < p < 2) and the Porous medium equation ((N-2/N)(+) < m < 1). In this range of the parameters p and m, we are in the so called fast diffusion case. We prove that the initial mass is preserved for all the times.

Abstract

In this paper we deal with the Cauchy problem associated to a class of quasilinear singular parabolic equations with L-infinity coefficients, whose prototypes are the p-Laplacian (2N/N+1 < p < 2) and the Porous medium equation ((N-2/N)(+) < m < 1). In this range of the parameters p and m, we are in the so called fast diffusion case. We prove that the initial mass is preserved for all the times.
