14 PROPAGATION PROPERTIES
Juan Luis Vázquez
This chapter introduces a study of the properties of the support and the free boundary of the solution in a several dimensional setting. It discusses in detail the property of finite propagation and its consequences for the PME. Attention is focused on non-negative solutions.
Keywords: propagation properties, waiting times, Cauchy problem, heat equation, whole space, free boundary
