Past Events

Translation surfaces given by gluing two identical tori along a slit have genus two and two cone-type singularities of angle $4\pi$. There is a distinguished set of trajectories called saddle connections that are the straight lines trajectories...

The COVID-19 global pandemic has led to unprecedented public interest in mathematical modelling as a tool to understand the dynamics of disease spread and predict the impact of public health interventions. In this pair of talks, we will describe how...

This event is being held virtually, below is the schedule: 9:30 to 10:30, Niny Arcila Maya (UBC) Decomposition of Azumaya Algebras Abstract: An Azumaya algebra of degree n over X is a bundle of algebras over X that is locally isomorphic to the matrix...

Filmed in Canada, Iran, and the United States, Secrets of the Surface: The Mathematical Vision of Maryam Mirzakhani examines the life and mathematical work of Maryam Mirzakhani, an Iranian immigrant to the United States who became a superstar in her...

Process calculus is a family of related approaches to formally model concurrent systems, e.g. Pi-calculus which pass channels as data along other channels; Ambient calculus which models distributed and mobile computations. Rho Calculus (Reflective...

We prove the last open case of the conjecture on the possible values of the first isotropy index of an anisotropic quadratic form over a field. It was initially stated by Detlev Hoffmann for fields of characteristic not 2 and then extended to...

Classical results of Dobrushin and Lanford-Ruelle establish, in rough terms, that for a local energy function on a subshift without too much long-range order, the translation-invariant Gibbs measures are precisely the equilibrium measures. There are...

A variety of cut-and-paste techniques is being developed to study Khovanov, Heegaard Floer and instanton homologies. We will describe one of such techniques, centered around immersed curves in surfaces. First, we will give an overview of existing...

Until very recently most cancer biologists operated with the assumption that the most common route to metastasis involved cells of the primary tumor transforming to a motile single-cell phenotype via complete EMT (the epithelial-mesenchymal...
