The Cauchy Problem for Ut = Delta u(m) When 0 < m < 1.
Abstract
This paper deals with the Cauchy problem for the nonlinear diffusion equation (fast diffusion case). We prove that there exists a global time solution for any locally integrable function u sub o: hence, no growth condition at infinity for u sub o is required. Moreover the solution is shown to be unique in that class. Keywords; Cauchy problem, nonlinear diffusion, initial-value problem, regularizing effects.
