While not all-encompassing, these topics represent major approaches to the theory of partial differential equations and systems, and should be of significant interest to graduate students and researchers. Two appendices have been included to provide a good gauge of the prerequisites for this book and make it reasonably self-contained. A notable strength of the book is that it contains a large number of substantial examples. Exercises for the reader are also included. Therefore, this book is suitable as a textbook for graduate students who have already had an introductory course on PDE and some familiarity with functional analysis and nonlinear functional analysis, and as a reference for researchers. 606 $aDifferential equations 606 $aFunctional analysis 606 $aBiomathematics 606 $aPopulation biology 606 $aDifferential Equations 606 $aFunctional Analysis 606 $aMathematical and Computational Biology 606 $aPopulation Dynamics 615 0$aDifferential equations. 615 0$aFunctional analysis. 615 0$aBiomathematics. 615 0$aPopulation biology. 615 14$aDifferential Equations. 615 24$aFunctional Analysis. 615 24$aMathematical and Computational Biology. 615 24$aPopulation Dynamics. 676 $a515.35 700 $aWang$b Mingxin$01738083 701 $aPang$b Peter Y.
