双曲3-单形反射群的代数K理论

Algebraic K-theory of hyperbolic 3-simplex reflection groups

J. -F. Lafont, I. J. Ortiz

摘要:

双曲3-单形反射群是作为双曲3-空间的等距群中的格而产生的考克斯特群,其基本区是测地线单形(可能具有一些理想顶点)。这些群的分类是已知的,有9个上紧的例子,23个非上紧的例子。给出了所有双曲3-单形反射群的整群环的下代数K理论的完整计算。

英文摘要:

A hyperbolic 3-simplex reflection group is a Coxeter group arising as a lattice in the isometry group of hyperbolic 3-space, with fundamental domain a geodesic simplex (possibly with some ideal vertices). The classification of these groups is known, and there are exactly 9 cocompact examples, and 23 non-cocompact examples. We provide a complete computation of the lower algebraic K-theory of the integral group ring of all the hyperbolic 3-simplex reflection groups.
