{"product_id":"9781475714654","title":"Progress in Mathematics","description":"\u003ch1\u003eProgress in Mathematics\u003c\/h1\u003e \u003ch2\u003eHelgason, Sigurdur\u003c\/h2\u003e \u003cp\u003eThe first edition of this book has been out of print for some time and I have decided to follow the publisher's kind suggestion to prepare a new edition. Many examples with explicit inversion formulas and range theo­ rems have been added, and the group-theoretic viewpoint emphasized. For example, the integral geometric viewpoint of the Poisson integral for the disk leads to interesting analogies with the X-ray transform in Euclidean 3-space. To preserve the introductory flavor of the book the short and self-contained Chapter Von Schwartz' distributions has been added. Here §5 provides proofs of the needed results about the Riesz potentials while §§3-4 develop the tools from Fourier analysis following closely the account in Hormander's books (1963] and [1983]. There is some overlap with my books (1984] and [1994b] which however rely heavily on Lie group theory. The present book is much more elementary. I am indebted to Sine Jensen for a critical reading of parts of the manuscript and to Hilgert and Schlichtkrull for concrete contributions men­ tioned at specific places in the text. Finally I thank Jan Wetzel and Bonnie Friedman for their patient and skillful preparation of the manuscript.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2013-10-09\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9781475714654\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-1-4757-1463-0\u003c\/p\u003e \u003cp\u003eDimensions: 229cm x152cm\u003c\/p\u003e \u003cp\u003ePages: 193\u003c\/p\u003e ","brand":"Springer US","offers":[{"title":"Default Title","offer_id":45987389702284,"sku":"9781475714654","price":134.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9781475714654.jpg?v=1775736551","url":"https:\/\/lateknightbooks.com\/products\/9781475714654","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
