摘要：
It is the aim of this article to give a detailed calculation of the number of cusps of an arithmetic subgroup of SL2(D) where D is a central simple division algebra over an algebraic number field. We show how this number of cusps corresponds to the class number of D. (C) 2017 Elsevier Inc. All rights reserved.
