Part of Functor Categories for Groups meeting supported by LMS

A group is said to be of type Fn if it admits a classifying space with compact n-skeleton. We will consider the class of Röver-Nekrachevych groups, a class of groups built out of self-similar groups and Higman-Thompson groups, and use them to produce a simple group of type Fn+1 but not of type Fn for each n. These are the first known examples for n > 2. This is a joint work with Stefan Witzel and Matthew C. B. Zaremsky.
