In fact, it was a starting point of new constructions associating C*-algebras to simple objects like groups, semigroups and rings. In this book, we present a natural continuation of that work, we construct the same C*-algebra for endomorphisms with infinite cokernel. We use the subset structure of the group to index interesting projections in the C*-algebra and present interesting connections with the semigroup C*-algebras defined by Xin Li. We also calculate some K-groups associated to such constructions.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786138825715\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786138825715","offer_id":40149463760989,"sku":"9786138825715","price":59.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/abb3aa2a-3f56-4f6e-bbb3-43a8023785a8.jpg?v=1773208946","url":"https:\/\/shop.autorenwelt.de\/products\/c-algebras-associated-with-endomorphisms-of-groups-von-felipe-vieira","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
