Groups with exotic finiteness properties from complex Morse theory
Claudio Llosa Isenrich, Pierre Py
Recent constructions have shown that interesting behaviours can be observed in the finiteness properties of Kähler groups and their subgroups. In this work, we push this further an…

Dehn functions of coabelian subgroups of direct products of groups
Robert Kropholler, Claudio Llosa Isenrich
We develop new methods for computing the precise Dehn functions of coabelian subgroups of direct products of groups, that is, subgroups which arise as kernels of homomorphisms from…

Residually free groups do not admit a uniform polynomial isoperimetric function
Claudio Llosa Isenrich, Romain Tessera
We show that there is no uniform polynomial isoperimetric function for finitely presented subgroups of direct products of free groups, by producing a sequence of subgroups $G_r\leq…
