Abstract:
This paper is concerned with the Hölder estimates of weak solutions of the Cauchy problem for the general degenerate parabolic equations
with the initial data , where the diffusion function can be a constant on a nonzero measure set, such as the equations of two-phase Stefan type. Some explicit Hölder exponents of the composition function with respect to the space variables are obtained by using the maximum principle.
