The present book pursues the program by introducing new ideas and techniques, giving a systematic and detailed treatment in the case of orthogonal groups of real rank one, which will serve as models for further research in other settings.\u003c\/div\u003e\u003cdiv\u003eIn connection to automorphic forms, this work includes a proof for a multiplicity conjecture by Gross and Prasad for tempered principal series representations in the case (\u003ci\u003eSO\u003c\/i\u003e(\u003ci\u003en\u003c\/i\u003e + 1, 1), \u003ci\u003eSO\u003c\/i\u003e(\u003ci\u003en\u003c\/i\u003e, 1)). The authors propose a further multiplicity conjecture for nontempered representations.\u003c\/div\u003e\u003cdiv\u003eViewed from differential geometry, this seminal work accomplishes the classification of all conformally covariant operators transforming differential forms on a Riemanniann manifold \u003ci\u003eX\u003c\/i\u003e to those on a submanifold in the model space (\u003ci\u003eX\u003c\/i\u003e, \u003ci\u003eY\u003c\/i\u003e) = (\u003ci\u003eS\u003c\/i\u003e\u003csup\u003e\u003ci\u003en\u003c\/i\u003e\u003c\/sup\u003e, \u003ci\u003eS\u003csup\u003en\u003c\/sup\u003e\u003c\/i\u003e\u003csup\u003e-1\u003c\/sup\u003e). Functional equations and explicit formulæ of these operators are also established.\u003c\/div\u003eThis book offers a self-contained and inspiring introduction to the analysis of symmetry breaking operators for infinite-dimensional representations of reductive Lie groups. This feature will be helpful for active scientists and accessible to graduate students and young researchers in representation theory, automorphic forms, differential geometry, and theoretical physics.\u003cbr\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2018-12-28\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9789811329005\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-981-13-2901-2\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 344\u003c\/p\u003e ","brand":"Springer Nature Singapore","offers":[{"title":"Default Title","offer_id":45369835356300,"sku":"9789811329005","price":44.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9789811329005.jpg?v=1775675688","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9789811329005","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
