{"product_id":"harmonic-analysis-and-representation-theory-alessandro-fig-talamanca-9780521424448","title":"Harmonic Analysis and Representation Theory for Groups Acting on Homogenous Trees","description":"These notes treat in full detail the theory of representations of the group of automorphisms of a homogeneous tree. The unitary irreducible representations are classified in three types: a continuous series of spherical representations; two special representations; and a countable series of cuspidal representations as defined by G.I. Ol'shiankii. Several notable subgroups of the full automorphism group are also considered. The theory of spherical functions as eigenvalues of a Laplace (or Hecke) operator on the tree is used to introduce spherical representations and their restrictions to discrete subgroups. This will be an excellent companion for all researchers into harmonic analysis or representation theory.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Alessandro Figá-Talamanca, Claudio Nebbia\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 0521424445\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9780521424448\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Cambridge University Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 06\/28\/1991\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 164\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.56lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 5.98w x 0.42d","brand":"Alessandro Figá-Talamanca","offers":[{"title":"Paperback","offer_id":44056266572031,"sku":"9780521424448","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_94f438ab-6dca-42e6-8094-a9cd3417aac9.jpg?v=1685040413","url":"https:\/\/www.whiterainbookhouse.com\/products\/harmonic-analysis-and-representation-theory-alessandro-fig-talamanca-9780521424448","provider":"WR Book House","version":"1.0","type":"link"}
