{"product_id":"graph-groupoids-and-their-topology-adrian-wilson-9783639007480","title":"Graph Groupoids and their Topology","description":"The book investigates graph groupoids and the path spaces associated with their unit spaces. Three main questions are solved. For the first, a natural question that was asked by A.Kumjian in the case of the Cuntz graph was how the topological space X relates to an earlier topological space investigated by J. Renault (Orleans). I show that the two topological spaces are homeomorphic and so can be identified. I then discuss the graph groupoid in the general case. For this investigation, it is important to be able to use the axiomatic approach to groupoids, and I show that this is equivalent to the usual definition of a groupoid as a \"small category with inverses\". This proof of this equivalence answers the second main question. The last is to construct the graph groupoid and prove that it is a second countable, locally compact, Hausdorff groupoid.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Adrian Wilson\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3639007484\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783639007480\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag Dr. Mueller E.K.\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/30\/2008\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 84\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.27lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.17d","brand":"Adrian Wilson","offers":[{"title":"Paperback","offer_id":48113835507967,"sku":"9783639007480","price":52.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_bf9a8f4b-93b6-4f0e-8772-e07d964040c0.jpg?v=1769617497","url":"https:\/\/www.whiterainbookhouse.com\/products\/graph-groupoids-and-their-topology-adrian-wilson-9783639007480","provider":"WR Book House","version":"1.0","type":"link"}
