Fusion systems have emerged as a powerful conceptual framework that encapsulates the conjugation relationships among p-subgroups of finite groups. This categorical approach not only unifies aspects of ...

Transactions of the American Mathematical Society, Vol. 362, No. 2 (FEBRUARY 2010), pp. 847-858 (12 pages) We use the geometry of the Davis complex of a Coxeter group to investigate finite index ...

In this course we will consider the structure of (infinite) groups. For this, we will study actions of groups on interesting topological and metric spaces. The geometry of these spaces can be used to ...

This is a preview. Log in through your library . This monthly journal, published since 1900, is devoted entirely to research in pure and applied mathematics, and, in general, includes longer papers ...

The aim of the seminar is to understand the structure and theory of the isometry groups of CAT(0)-spaces and their lattices. The papers on discrete subgroups and structure theory by Caprace and Monod ...
