"In and around stable homotopy groups of spheres"
Angelos Koutsianas, University of British Columbia
"Solving generalized Fermat equations with Frey hyperelliptic curves"
In this talk, I will talk about Darmon's program and the resolution of the generalized Fermat equation of signature (p,p,5) using Frey hyperelliptic curves. This is joint work with Imin Chen (Simon Fraser University).

"The category of cobordisms (Part III)"
We specialize to the 2cobordism category, and work towards developing a set of generators and relations.

"The size of complementary sets"

"An introduction to the Laplacian operator on a metrized graph"
In this presentation we shall attempt to give a self contained introduction to finite metrized graphs. Following this introduction we shall discuss how to define a Laplacian operator on a finite metrized graph and discuss its basic properties.

"Density of polynomials with squarefree discriminant II"
In this talk, we will discuss the squarefree sieve for discriminants of arbitrary polynomials. We will find that there are striking differences between odd and even degree polynomials, where additional techniques of counting on varieties will be required for the latter. This is joint work with Manjul Bhargava and Arul Shankar.

"The category of cobordisms (Part II)"
We will continue to discuss the category of cobordisms, along with more examples.

"Compactification of Monopole Moduli Spaces"
Monopole's dynamic is well approximated by the geodesic motion on its moduli space. This provided the initial motivation for studying monopole moduli spaces. Recently, these spaces acquired new significance as they deliver numerous examples of gravitational instantons and of spaces of vacua of quantum field theories. In this light the L2 cohomology of these spaces is particularly important.

"Deformation theory of nearly G_2 manifolds  2"
In this talk we will prove some results about the cohomology of nearly G_2 manifolds which we will use to define the space of first order deformation of a nearly G_2 structure. We will then prove that it is an eigenspace of the Laplace operator. Time permitting we will also define the second order deformations and their formulation. This talk is based on a joint work in progress with Shubham Dwivedi.

"The category of cobordisms"
In this talk, we’ll discuss how nmanifolds considered up to cobordism form a category, as well as some of the subtleties involved.

"Introduction to Arakelov Theory"
I will introduce the basic concepts of Arakelov theory with a focus on arithmetic surfaces.

"Estimates for metrics of constant Chern scalar curvature"
We discuss the existence problem of constant Chern scalar curvature metrics on a compact complex manifold. We prove a priori estimates for these metrics conditional on an upper bound on the entropy, extending a recent result by ChenCheng in the K\"ahler setting.

"Loosely embeddable metric spaces"
Embedding finite metric spaces isometrically into Hilbert spaces has elicited some interest outside of pure mathematics due to applications to fields like computer vision, machine learning, the structure of networks and other such areas.
