This book introduces a new method for the study of the asymptotic behavior of solutions to evolution partial differential equations; much of the text is dedicated to the application of this method to a wide class of nonlinear diffusion equations. The underlying theory hinges a new stability result, formulated in the abstract setting of infinite-dimensional dynamical systems, which states that under certain hypotheses, the $$\omega$$-limit set of a perturbed dynamical system is stable under arbitrary asymptotically small perturbations.
The stability theorem is examined in detail in the first chapter, followed by a review of basic results and methods – many original to the authors – for the solution of nonlinear diffusion equations. Further chapters provide a self-contained analysis of specific equations, with carefully constructed theorems, proofs, and references. In addition to the derivation of interesting limiting behaviors, the book features a variety of estimation techniques for solutions of semi- and quasilinear parabolic equations.
