Algebraic Geometry Seminar

Monday, January 23, 2017 - 11:30 AM EST

Matthew Satriano, Pure Mathematics, University of Waterloo

"Hodge theory for combinatorial geometries"

Now that we have an overview of the main results of Adiprasito–Huh–Katz, we start going into the details.

Geometric Analysis Seminar

Monday, January 23, 2017 - 2:30 PM EST

Akos Nagy, Department of Pure Mathematics, University of Waterloo

"Seiberg--Witten equation with multiple spinors in dimension 3 --- Part I"

Following Haydys and Walpuski, I will introduce a generalization of the SW equations on 3-manifolds, and prove a compactness theorem for the moduli space of solutions.

In the first talk, I will define the problem (the SW equations with multiple spinors), state the main theorem of the paper, and prove a couple a priori estimates.

Computability Learning Seminar

Tuesday, January 24, 2017 - 3:00 PM EST

Jonny Stephenson, Pure Mathematics, University of Waterloo

"The back-and-forth property and uniform computable categoricity"

Cantor's back-and-forth argument gives a condition allowing one to construct isomorphisms between different copies of mathematical structures by a process of finite extension. We will give a condition which shows when such a procedure can be carried out, as well as demonstrating a link between back-and-forth procedures, effective atomicity, and uniform computable categoricity of structures.

Geometric Analysis Seminar

Wednesday, January 25, 2017 - 2:30 PM EST

Shubham Dwivedi, Pure Mathematics, University of Waterloo

"The Monotonicity formula"

We will continue our discussion of minimal submanifolds. After discussing some consequences of the First Variation formula, we will state and prove the Monotonicity formula of volume for minimal submanifolds. We will also state (and might prove) the coarea formula.

Number Theory Seminar

Thursday, January 26, 2017 - 1:30 PM EST

Sacha Mangerel, University of Toronto

"Some Applications of Pretentiousness in the Theory of Dirichlet Characters"

Sieve Methods Learning Seminar

Thursday, January 26, 2017 - 4:00 PM EST

Ertan Elma, Pure Mathematics, University of Waterloo

We will start reading the book 'An Introduction to Sieve Methods and their Applications' by A.C. Cojocaru and M.R. Murty. In this first talk, we will cover some basic results from the first chapter and if time permits we will start Gallagher's 'larger' sieve.  

If you are interested in these talks, please send an e-mail to eelma@uwaterloo.ca for some possible time/room changes and for some documents that we may share.
