    The existence of time local C-solutions is shown for Cauchy problem of the porous medium equations. Our arguments rely on the "L-energy method" developed in our previous paper [16] and a new method based on the theory of evolution equations in the L2-framework which enables us to handle with porturbations which can be decomposed into monotone parts and small parts in Sobolev spaces of higher order.
