Minimum-Cost Coverage of Point Sets by Disks
Esther M. Arkin, Herve Broennimann, Jeff Erickson +5
We consider a class of geometric facility location problems in which the goal is to determine a set X of disks given by their centers (t_j) and radii (r_j) that cover a given set o…

Bestvina's normal form complex and the homology of Garside groups
Ruth Charney, John Meier, Kim Whittlesey
A Garside group is a group admitting a finite lattice generating set D. Using techniques developed by Bestvina for Artin groups of finite type, we construct K(π,1)s for Garside gro…

Normal all pseudo-Anosov subgroups of mapping class groups
Kim Whittlesey
We construct the first known examples of nontrivial, normal, all pseudo-Anosov subgroups of mapping class groups of surfaces. Specifically, we construct such subgroups for the clos…
