Masaki Ohnuma, Koh Sato · Hokkaido University Collection of Scholarly and Academic Papers (Hokkaido University) · 1997
We consider singular degenerate parabolic equations including the p-Laplace diffusion equation. We establish a comparison priciple which is a natural extension of the paper [12] by Ishii and Souganidis. Once we get a comparison priciple we can construct the unique global-in-time solution to the Cauchy problem for the p-Laplace diffution equation. The solution is bounded, uniformly continuous [0,T）× R N if the initial data is bounded, unformaly continuous on R N.
