"Heegaard diagrams of three-manifolds"

We will represent handle decompositions of three-manifolds diagramatically, and relate them to Heegaard splittings. This will serve as a precursor for Kirby diagrams.

"Yet another proof of the Riemann hypothesis"

In the last few months, I have developed a hobby, which is to find proofs (or disproofs?!) of the Riemann hypothesis. In this talk, I will be sharing some of my favourite ones!

M. Ram Murty, Queen's University

"Brain Network Hubs and Markov Processes"

A new chapter of interdisciplinary research between neuroscience and graph theory has emerged in the last 20 years. In recent joint work with neuroscientist A. N. Prasad, we proposed a model using graph theory and Markov chains to identify "brain hubs" in the neural networks of organisms. We will survey this work and underline some future directions. The talk will be accessible to a general audience.

"Arithmetical Functions of Several Variables"

We will survey several results in the theory of arithmetical functions of several variables, a subject that is not often treated in number theory textbooks though it should be!

"Berkovich space"

Dynamics on the Berkovich projective line has applications in arithmetic geometry and intersection theory.  We give a brief overview of Berkovich space in this talk.
