Sturm?Liouville theory has applications in partial differential equations and mathematical physics. Examples include classical PDEs such as the heat and wave equations. Written by leading experts, this book provides a modern, systematic treatment of the theory. The main topics are the spectral theory and eigenfunction expansions for Sturm?Liouville equations, as well as scattering theory and inverse spectral theory. It is the first book offering a complete account of the left-definite theory for Sturm?Liouville equations. The modest prerequisites for this book are basic one-variable real analysis, linear algebra, as well as an introductory course in complex analysis. More advanced background required in some parts of the book is completely covered in the appendices. With exercises in each chapter, the book is suitable for advanced undergraduate and graduate courses, either as an introduction to spectral theory in Hilbert space, or to the spectral theory of ordinary differential equations. Advanced topics such as the left-definite theory and the Camassa?Holm equation, as well as bibliographical notes, make the book a valuable reference for experts. 410 0$aUniversitext,$x0172-5939 606 $aOperator theory 606 $aCalculus 606 $aMathematical analysis 615 0$aOperator theory. 615 0$aCalculus. 615 0$aMathematical analysis. 676 $a515.352 700 $aBennewitz$b Christer$f1943-$059796 702 $aWeikard$b Rudi$f1958- 702 $aBrown$b Malcolm 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996418187103316 996 $aSpectral and Scattering Theory for Ordinary Differential Equations$91889267 997 $aUNISA
