More precisely one has a class of concrete objects, a rule to associate a 3-manifold to each object, and a set of moves such that if two objects define the same 3-manifold then they are obtained from each other by a finite number of these moves. In this work I provide a calculus for compact 3-manifolds with boundary based on standard spines, and discuss related questions; in particular, I introduce a general framework for the definition of invariants based on this calculus.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Edizioni della Normale\u003c\/p\u003e \u003cp\u003ePublication Date: 1995-10-01\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9788876422560\u003c\/p\u003e \u003cp\u003eDOI: \u003c\/p\u003e \u003cp\u003eDimensions: 240cm x170cm\u003c\/p\u003e \u003cp\u003ePages: 61\u003c\/p\u003e ","brand":"Scuola Normale Superiore","offers":[{"title":"Default Title","offer_id":46266263634060,"sku":"9788876422560","price":13.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9788876422560.jpg?v=1770817678","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9788876422560","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
