Arithmetic Geometry Learning Seminar Organisational Meeting

We’re starting up an arithmetic geometry seminar, online, and we’d like to include anyone who wants to participate. The starting point will be the book by Hindry and Silverman on Diophantine Geometry, but we may quickly diverge into other directions. I don’t expect this to be the regular meeting time – the most important part of the first meeting will be to decide on a regular meeting time. So if you can’t make it to the organizational meeting, please email David McKinnon to say what your scheduling constraints are.

Geometry & Topology Seminar

Oğuz Şavk, Bogaziçi University

"Classical and new plumbings bounding contractible manifolds and homology balls"

A central problem in low-dimensional topology asks which homology 3-spheres bound contractible 4-manifolds and homology 4-balls. In this talk, we address this problem for plumbed 3-manifolds and we present the classical and new results together. Our approach is based on Mazur’s famous argument which provides a unification of all results in a fairly simple way.

Geometry Working Seminar

Christopher Lang, Department of Pure Mathematics, University of Waterloo

"On the charge density and asymptotic tail of a monopole"

Pure Math Colloquium

Guillaume Aubrun, Université Claude Bernard Lyon 1

"Entangleability of cones"

Learning Seminar on Probabilistic Aspects of the Thompson Monoid

Arundhathi Krishnan, Department of Pure Mathematics, University of Waterloo

We will continue our discussion about monoids presented by generators and relations. What comes next is to look at the notion of normal form for an element in such a monoid, and at how normal forms can be used to prove the cancellativity property.
