{"product_id":"functorial-knot-theory-yetter-david-n-9789810244439","title":"Functorial Knot Theory","description":"\u003cp\u003eAlmost since the advent of skein-theoretic invariants of knots and links (the Jones, HOMFLY, and Kauffman polynomials), the important role of categories of tangles in the connection between low-dimensional topology and quantum-group theory has been recognized. The rich categorical structures naturally arising from the considerations of cobordisms have suggested functorial views of topological field theory.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cp\u003eThis book begins with a detailed exposition of the key ideas in the discovery of monoidal categories of tangles as central objects of study in low-dimensional topology. The focus then turns to the deformation theory of monoidal categories and the related deformation theory of monoidal functors, which is a proper generalization of Gerstenhaber's deformation theory of associative algebras. These serve as the building blocks for a deformation theory of braided monoidal categories which gives rise to sequences of Vassiliev invariants of framed links, and clarify their interrelations.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Yetter David N\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 9810244436\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9789810244439\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e World Scientific Publishing Company\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/28\/2001\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 236\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Hardcover\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 1.01lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.60h x 6.10w x 0.80d","brand":"Yetter David N","offers":[{"title":"Hardcover","offer_id":48446700191999,"sku":"9789810244439","price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_25a4a8d4-180f-49b2-b7b2-84e4c3209e17.jpg?v=1777226372","url":"https:\/\/www.whiterainbookhouse.com\/products\/functorial-knot-theory-yetter-david-n-9789810244439","provider":"WR Book House","version":"1.0","type":"link"}
