Events - February 2020

Friday, February 28, 2020 — 3:30 PM EST

Alex Rutar, Department of Pure Mathematics, University of Waterloo

"Geometric and Combinatorial Separation Conditions for Iterated Function Systems"

Friday, February 28, 2020 — 3:00 PM EST

Michael Klug, University of California Berkeley

"Concordance of homotopic spheres in 4-manifolds"

Wednesday, February 26, 2020 — 3:30 PM EST

Wilson Poulter, Department of Pure Mathematics, University of Waterloo

"Ultraproducts, Hyperreals, and Pseudofinite Graphs"

An ultraproduct is a construction used in mathematical logic to construct limits of first-order structures. Due to a result of Jerzy Los, the first-order properties of these limits is very well understood, allowing one to construct counter-examples as well as structures that are interesting in and of themselves.

Wednesday, February 26, 2020 — 2:30 PM EST

Brett Nasserden, Department of Pure Mathematics, University of Waterloo

"An introduction to the Laplacian operator on a metrized graph: Part 2"

We will continue our discussion of harmonic analysis on a finite metrized graph. The goal is to finish the introduction to the theory and go over some explicit examples.

Andrew Staal, Department of Pure Mathematics, University of Waterloo

"Reducibility of Varieties of Commuting Matrices"

We will present some well-known results on reducibility of the varieties C(k,n) of commuting k-tuples of nxn-matrices.  In particular, we will discuss the Motzkin—Taussky Theorem proving irreducibility of C(2,n) and Guralnick’s Theorem, which shows that C(3,n) is reducible when n ≥ 29.  

MC 5413

This week, we will further talk about the generators and relations for 2Cob.

"In and around stable homotopy groups of spheres"

Tuesday, February 18, 2020 — 1:30 PM EST

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).

Patrick Naylor, Department of Pure Mathematics, University of Waterloo

"The category of cobordisms (Part III)"

We specialize to the 2-cobordism category, and work towards developing a set of generators and relations.  

MC 5417

Friday, February 14, 2020 — 3:30 PM EST

Kathryn Hare, Department of Pure Mathematics, University of Waterloo

"The size of complementary sets"

Wednesday, February 12, 2020 — 2:30 PM EST

Brett Nasserden, Department of Pure Mathematics, University of Waterloo

"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. 

MC 5403

Tuesday, February 11, 2020 — 1:30 PM EST

Jerry Wang, Department of Pure Mathematics, University of Waterloo

"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.

MC 5417

Tuesday, February 11, 2020 — 10:30 AM EST

Jinhe Ye, University of Notre Dame

"A model theoretic adic space"

Tuesday, February 11, 2020 — 10:00 AM EST

Patrick Naylor, Department of Pure Mathematics, University of Waterloo

"The category of cobordisms (Part II)"

We will continue to discuss the category of cobordisms, along with more examples. 

MC 5417

Monday, February 10, 2020 — 4:00 PM EST

Marco Gualtieri, University of Toronto 

"From generalized Kahler geometry to noncommutative algebra"

Friday, February 7, 2020 — 3:30 PM EST

Adam Humeniuk, Department of Pure Mathematics, University of Waterloo

"On C*-Envelopes of Semicrossed Products"

Friday, February 7, 2020 — 10:00 AM EST

Note: Special time and room

Sergey Cherkis, University of Arizona

"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.

Thursday, February 6, 2020 — 4:30 PM EST

Benjamin Anderson-Sackaney, Department of Pure Mathematics, University of Waterloo

"Honeycombs and the Horn Problem"

Wednesday, February 5, 2020 — 2:30 PM EST
Andrej Vukovic, Department of Pure Mathematics, University of Waterloo
 
"Potential Theory for Metric Trees"
 
We discuss potential theory for general metric trees and explain how to apply it in our study of the valuative tree.
 
MC 5403
Tuesday, February 4, 2020 — 1:30 PM EST
Stanley Xiao, University of Toronto
    
"The density of power-free values of polynomials"
    
In this talk we show that any polynomial $F(x_1, \cdots, x_n)$ with integer coefficients and degree $d \geq 3$ and which satisfy basic necessary conditions take on the expected density of $k$-free values, provided that $k \geq \min\{d-1, 3d/4\}$. This generalizes results of Hooley and Browning, who showed the same result with $n = 1$. This is joint work with K. Lapkova. 
 
Tuesday, February 4, 2020 — 11:00 AM EST
Eric Boulter, Department of Pure Mathematics, University of Waterloo
    
"Vector Bundles on Non-Kähler Elliptic Fibre Bundles"
    
In this talk we will discuss non-Kähler complex surfaces which occur as elliptic fibre bundles, and some invariants of holomorphic vector bundles on these surfaces.
