Regularity of viscosity solutions to a degenerate nonlinear Cauchy problem Original Research Article

This paper is concerned with the regularity of certain weak solutions to the Cauchy problem in RNRN for a degenerate nonlinear parabolic equation. We get the Hölder regularity of the weak solution when the parameter View the MathML sourceγ≥N−1 and improve the parameter’s region from View the MathML sourceγ≥2N−1 to View the MathML sourceγ≥N−1 since View the MathML sourceN−1<2N−1.
