{"product_id":"almost-bieberbach-groups-affine-and-polynomial-structures-von-karel-dekimpe","title":"Almost-Bieberbach Groups: Affine and Polynomial Structures","description":"Starting from basic knowledge of nilpotent (Lie) groups, an algebraic theory of almost-Bieberbach groups, the fundamental groups of infra-nilmanifolds, is developed. These are a natural generalization of the well known Bieberbach groups and many results about ordinary Bieberbach groups turn out to generalize to the almost-Bieberbach groups. Moreover, using affine representations, explicit cohomology computations can be carried out, or resulting in a classification of the almost-Bieberbach groups in low dimensions. The concept of a polynomial structure, an alternative for the affine structures that sometimes fail, is introduced.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783540618997\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783540618997","offer_id":39437028950109,"sku":"9783540618997","price":48.1,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e4a488c5-e5f6-4ea9-8f1d-36529fa58f4f.jpg?v=1772085287","url":"https:\/\/shop.autorenwelt.de\/products\/almost-bieberbach-groups-affine-and-polynomial-structures-von-karel-dekimpe","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
