Description
Second Order Parabolic Differential EqnThis book is an introduction to the general theory of second order parabolic differential equations, which model many important, time dependent physical systems. It studies the existence, uniqueness, and regularity of solutions to a variety of problems with Dirichlet boundary conditions and general linear and nonlinear boundary conditions by means of a priori estimates. The first seven chapters give a description of the linear theory and are suitable
This book is an introduction to the general theory of second order parabolic differential equations, which model many important, time-dependent physical systems. It studies the existence, uniqueness, and regularity of solutions to a variety of problems with Dirichlet boundary conditions and general linear and nonlinear boundary conditions by means of a priori estimates. The first seven chapters give a description of the linear theory and are suitable for a graduate course on partial differential equations. The last eight chapters cover the nonlinear theory for smooth solutions. They include much of the author's research and are aimed at researchers in the field. A unique feature is the emphasis on time-varying domains.Shipping Notes

Good value for the price.

Good quality for the price. Thinner than I would like but they do the job for a family with multiple kids, meals and spills.

Thin thin not very good, not good for dinner

They say online they are dinner napkins, but when they arrive they say Luncheon. These are so thin, not good at all unless you're eating a piece of toast .
