Connectivity Properties of Horospheres in Euclidean Buildings and Applications to Finiteness Properties of Discrete Groups
Kai-Uwe Bux, Kevin Wortman
Let G(O_S) be an S-arithmetic subgroup of a connected, absolutely almost simple linear algebraic group G over a global function field K. We show that the sum of local ranks of G de…
Some Remarks on the Braided Thompson Group BV
Kai-Uwe Bux, Dmitriy Sonkin
Matthew Brin and Patrick Dehornoy independently discovered a braided version BV of Thompson's group V. In this paper, we discuss some properties of BV that might make the group int…
Automorphisms of two-dimensional RAAGs and partially symmetric automorphisms of free groups
Kai-Uwe Bux, Ruth Charney, Karen Vogtmann
We compute the virtual cohomological dimension (VCD) of the group of partially symmetric outer automorphisms of a free group. We use this to obtain new upper and lower bounds on th…
SL(n,Z[t]) is not FP_{n-1}
Kai-Uwe Bux, Amir Mohammadi, Kevin Wortman
We prove the result from the title using the geometry of Euclidean buildings.
