Abstract. We prove precise decay in time estimates of the
total mass of a solution to the Cauchy problem for a
quasilinear degenerate parabolic equation with absorption
terms. The equation may involve additional terms whose behavior
at infinity is described by Wolf potentials.
Such estimates are given in terms of new critical exponents.
