{"product_id":"topology-and-combinatorics-of-3-manifolds-von-klaus-johannson","title":"Topology and Combinatorics of 3-Manifolds","description":"This book is a study of combinatorial structures of 3-mani- folds, especially Haken 3-manifolds. Specifically, it is concerned with Heegard graphs in Haken 3-manifolds, i.e., with graphs whose complements have a free fundamental group. These graphs always exist. They fix not only a combinatorial stucture but also a presentation for the fundamental group of the underlying 3-manifold. The starting point of the book is the result that the intersection of Heegard graphs with incompressible surfaces, or hierarchies of such surfaces, is very rigid. A number of finiteness results lead up to a ri- gidity theorem for Heegard graphs. The book is intended for graduate students and researchers in low-dimensional topolo- gy as well as combinatorial theory. It is self-contained and requires only a basic knowledge of the theory of 3-manifolds\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540590637\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783540590637","offer_id":39437489438813,"sku":"9783540590637","price":69.54,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d1e9848d-b531-4851-aaa2-1acb3059c5ef.jpg?v=1772172634","url":"https:\/\/shop.autorenwelt.de\/products\/topology-and-combinatorics-of-3-manifolds-von-klaus-johannson","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
