Geometry of the graphs of nonseparating curves: covers and boundaries
Alexander J. Rasmussen
We investigate the geometry of the graphs of nonseparating curves for surfaces of finite positive genus with potentially infinitely many punctures. This graph has infinite diameter…

WWPD elements of big mapping class groups
Alexander J. Rasmussen
We study mapping class groups of infinite type surfaces with isolated punctures and their actions on the loop graphs introduced by Bavard-Walker. We classify all of the mapping cla…
