The purpose of this paper is to find a doubly nonlinear parabolic equation of fast diffusion in a bounded domain.,For positive and bounded initial data, the authors study the initial zero-boundary value problem.,The findings of this study showed the complete extinction of a continuous weak solution at a finite time.,The extinction time is studied earlier but for the Laplacian case. The authors presented the finite extinction time for the case of p-Laplacian.
