A Brown Theorem for Dehn functions of graphs of groups

Claudio Llosa Isenrich, Jannis Weis

We prove an upper bound on the Dehn function of a group acting cellularly, cocompactly, and without inversions on a simply connected CW complex in terms of the Dehn functio…

Infinitely presented simple groups separated by homological finiteness properties

Claudio Llosa Isenrich, Eduard Schesler, Xiaolei Wu

Given a finitely generated linear group over , we construct a simple group that has the same finiteness properties as and admits as a quasi-retract. As…

measure equivalence of nilpotent groups

Thiebout Delabie, Claudio Llosa Isenrich, Romain Tessera

We classify compactly generated locally compact groups of polynomial growth up to measure equivalence (ME) for all . To achieve this, we combine rigidity results (pr…

Dehn functions of subgroups of products of free groups. Part II: Precise computations

Dario Ascari, Federica Bertolotti, Giovanni Italiano +2

We prove that the Bridson-Dison group has quartic Dehn function, thereby providing the first precise computation of the Dehn function of a subgroup of a direct product of free grou…

Profinite rigidity of Kähler groups: Riemann surfaces and subdirect products

Sam Hughes, Claudio Llosa Isenrich, Pierre Py +2

This paper establishes strong profinite rigidity results for Kähler groups, showing that certain groups are determined within the class of residually finite Kähler groups by their…

Explicit polynomial bounds on Dehn functions of subgroups of hyperbolic groups

Robert Kropholler, Claudio Llosa Isenrich, Ignat Soroko

In 1999 Brady constructed the first example of a non-hyperbolic finitely presented subgroup of a hyperbolic group by fibring a non-positively curved cube complex over the circle. W…
