Little change has been made in the text except that the para- graphs V-  4.5, VI-  4.3, and VI-  1.4 have been completely rewritten, and a number of minor errors, mostly typographical, have been corrected. The author would like to thank many readers who brought the errors to his attention. Due to these changes, some theorems, lemmas, and formulas of the first edition are missing from the new edition while new ones are added. The new ones have numbers different from those attached to the old ones which they may have replaced. Despite considerable expansion, the bibliography i not intended to be complete. Berkeley, April 1976 TosIO RATO Preface to the First Edition This book is intended to give a systematic presentation of perturba- tion theory for linear operators. It is hoped that the book will be useful to students as well as to mature scientists, both in mathematics and in the physical sciences.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":49738008527121,"sku":"NGR9783540586616","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ NEW \/ INGRAM","offer_id":51064555503889,"sku":"NIN9783540586616","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":51840241762577,"sku":"GOR010066840","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ NEW \/ INGRAM","offer_id":52129219248401,"sku":"NLS9783540586616","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ GOOD \/ SBYB","offer_id":53039784624401,"sku":"CIN354058661XG","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/354058661X.jpg?v=1753785506"},{"product_id":"short-introduction-to-perturbation-theory-for-linear-operators-book-tosio-kato-9781461257028","title":"A Short Introduction to Perturbation Theory for Linear Operators","description":"This book is a slightly expanded reproduction of the first two chapters (plus Introduction) of my book Perturbation Theory tor Linear Operators, Grundlehren der mathematischen Wissenschaften 132, Springer 1980. Ever since, or even before, the publication of the latter, there have been suggestions about separating the first two chapters into a single volume. I have now agreed to follow the suggestions, hoping that it will make the book available to a wider audience. Those two chapters were intended from the outset to be a comprehen­ sive presentation of those parts of perturbation theory that can be treated without the topological complications of infinite-dimensional spaces. In fact, many essential and. even advanced results in the theory have non­ trivial contents in finite-dimensional spaces, although one should not forget that some parts of the theory, such as those pertaining to scatter­ ing. are peculiar to infinite dimensions. I hope that this book may also be used as an introduction to linear algebra. I believe that the analytic approach based on a systematic use of complex functions, by way of the resolvent theory, must have a strong appeal to students of analysis or applied mathematics, who are usually familiar with such analytic tools.","brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":51027544932625,"sku":"","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":51027549094161,"sku":"NIN9781461257028","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ NEW \/ INGRAM","offer_id":52127361892625,"sku":"NLS9781461257028","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/1461257026.jpg?v=1751020220"},{"product_id":"on-the-eigenfunctions-of-many-particle-systems-in-quantum-mechanics-book-tosio-kato-9781017041033","title":"On the Eigenfunctions of Many-particle Systems in Quantum Mechanics","description":null,"brand":"WoB","offers":[{"title":"US \/ NEW \/ INGRAM","offer_id":52776541323537,"sku":"NIN9781017041033","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781017041033.jpg?v=1763911982"}],"url":"https:\/\/www.worldofbooks.com\/en-gb\/collections\/author-books-by-tosio-kato.oembed","provider":"World of Books ","version":"1.0","type":"link"}
