  10. 24. Almost planar finitely presented groups
    Joseph MacManus (University of Bristol)
    10/14/26, 2:30 PM

    Following Benjamini-Schramm, a graph is called 'almost planar' if it can be drawn in the plane such that every edge crosses at most a bounded number of edges, and a finitely generated group is called an 'almost planar group' if its Cayley graphs are almost planar graphs. Despite being a relatively well-studied class, the only known examples of such groups are those which virtually admit a...

  11. 25. Bounded cohomology, the Hausdorff property, and ultraproducts
    Alexis Marchand (Instytut Matematyczny Polskiej Akademii Nauk)
    10/14/26, 3:30 PM

    (Joint work with Piotr Nowak.) Bounded cohomology is a functional-analytic variant of group cohomology. Despite its many connections with geometry and topology, it can be a mysterious object. This talk will be about the property of bounded cohomology being Hausdorff. We will explain how this property can be read in asymptotic cohomology, yet another cohomology theory that was introduced...

  13. 21. Finiteness properties of automorphism groups
    Naomi Andrew (Laboratoire de Mathématiques d’Orsay)
    10/15/26, 9:30 AM

    Groups encode symmetries, and their automorphism groups encode the symmetries of the group themselves. So we can ask when "nice" properties of a group imply "nice" properties of its automorphisms. On the positive side, mapping class groups, GL(n,Z) and Out(F_n) are all finitely presented (in fact a stronger property: Type VF), and this can be analysed geometrically, using spaces built from...

  15. 26. Complete classification of the Dehn functions of Bestvina–Brady groups
    Jeronimo Garcia Mejia (University of Warwick)
    10/15/26, 12:00 PM

    Introduced by Bestvina and Brady in 1997, Bestvina–Brady groups form an important class of examples in geometric group theory and topology, known for having unusual finiteness properties. In this talk, I will focus on the Dehn functions of finitely presented Bestvina–Brady groups. The Dehn function of a group is a fundamental quasi-isometry invariant that, very roughly speaking, measures how...
