%0 Journal Article %T K-theory for ring C*-algebras - the case of number fields with higher roots of unity %A Xin Li %A Wolfgang L¨ąck %J Mathematics %D 2012 %I arXiv %R 10.2140/agt.2013.13.1 %X We compute K-theory for ring C*-algebras in the case of higher roots of unity and thereby completely determine the K-theory for ring C*-algebras attached to rings of integers in arbitrary number fields. %U http://arxiv.org/abs/1201.4296v2
