Mentor for MIORPA - the Mathematical Institute’s Online Research Projects with Africa

We are seeking mentors and projects for online research projects with Africa. This scheme matches mentors with Master’s-level students in sub-Saharan Africa who are not currently enrolled in a PhD programme; through a combination of research experience and skills training, the scheme aims to empower students to make competitive graduate applications in Africa and elsewhere.

Fibring, foliations and group theory

William Thomas
((Mathematical Institute University of Oxford))
Abstract
The phenomena of 3-manifolds fibring over S^1 has strong links with group theory. A particular instance of this is Stallings’s fibring theorem, which roughly says that a compact 3-manifold fibres over S^1 if and only if its fundamental group admits a nontrivial homomorphism to Z with finitely generated kernel. A manifold fibring over S^1 is in some sense generalised by having a (codimension 1) foliation, with the latter forming a far broader class of objects. As such, one cannot hope in general to see a foliation in the fundamental group of your manifold, and especially not in as nice a form as a group homomorphism! In this talk we will give a gentle introduction to the objects mentioned above, before introducing a particularly nice class of foliations introduced by Thurston which do in fact appear in the fundamental group in the form of a quasimorphism with strong geometric properties. Time permitting, I will mention some ongoing work with Paula Heim on the study of these quasimorphisms from the perspective of group theory and coarse geometry.
