Sinopsis

Focusing on stochastic porous media equations, this book places an emphasis onáexistence theorems, asymptotic behavior and ergodic properties of the associatedátransition semigroup. Stochastic perturbations of the porous media equation haveáreviously been considered by physicists, but rigorous mathematical existenceáresults have only recently been found.The porous media equation models a number of different physical phenomena,áincluding the flow of an ideal gas and the diffusion of a compressible fluid througháporous media, and also thermal propagation in plasma and plasma radiation.áAnother important application is to a model of the standard self-organized criticalityáprocess, called the 'sand-pile model' or the 'Bak-Tang-Wiesenfeld model'.The book will be of interest to PhD students and researchers in mathematics,áphysics and biology.
