Hi all, we hope you are holding up okay at home. Due to the circumstances, we’ve decided to postpone elections for the 2020-2021 Math Union Executive until the start of the new academic year. In the meantime, for the summer term and until the elections are run, we’re appointing an Interim Executive. Your two Interim Executives are Curtis Grant and Martin Shoosterman.

If you have questions or concerns, feel free to email us at mu@math.toronto.edu. Stay strong and healthy everyone!


Hi all, due to current events, we will be cancelling our events for the remainder of the semester. This tentatively includes elections for the Math Union executive for 2020-2021; we are waiting for word from the Arts & Science Student Union to give final word on how we will proceed with elections.

If you have questions or concerns, feel free to email us at mu@math.toronto.edu. Stay safe!

Micheal Pawliuk: A History of Functions

We’ll have a Math Union talk next week on Tuesday, March 10 at 6:10pm in BA 6183. Prof. Micheal Pawliuk will be speaking about the history of functions! As always, there will be food.

Title: A History of Functions

Abstract: What is a function? Our current definition is surprisingly recent, and it figuring it out was a result of important questions in mathematics and physics. Updating our definition resulted in having to “redo” a bunch of seemingly solved mathematics.

We’ll trace the history of functions from the mid 1800s forward to the birth of topology.

Kasun Fernando: Statistical Properties of Dynamical Systems


There will be a Math Union lecture on Wednesday, March 4, at 5:10pm in BA024. Kasun Fernando will be speaking about the statistical properties of dynamical systems. Food will be served!


Title: Statistical Properties of Dynamical Systems


Abstract: Since the work of Boltzmann in statistical mechanics, physicists and mathematicians alike were interested in looking at deterministic chaotic systems with a probabilistic eye. Later, with the mathematical foundations laid out by Birkhoff, Kolmogorov and von Neumann, the systematic study of statistical properties of dynamical systems aka Ergodic Theory started to flourish. My talk will be a brief introduction to this probabilistic approach to making sense of chaotic phenomena.

Christian Ketterer: Synthetic curvature bounds – A friendly introduction

Hi everyone! We will be having our first talk of the semester on Tuesday, January 28th, 2019 at 4:10pm. A post doc Christian Ketterer will be speaking.

Details of the room will be announced shortly!

Title: Synthetic curvature bounds – A friendly introduction

Abstract: In this talk I will explain the concepts of synthetic sectional curvature bounds and synthetic lower Ricci bounds and the ideas behind them. Synthetic lower Ricci bounds originated in the last 20 years from the encounter of several mathematical fields, including Riemannian Geometry, Optimal Transport and Information Theory. I will briefly describe these fields and show how they mixed.

Graduate Applications Workshop – this Thursday

Hi everyone! Just a reminder that this Thursday, Jan 9, there will be a graduate applications workshop at 4pm in BA6183. For those of you who are applying to graduate schools now or are interested in applying in the future, this is a great opportunity to hear about the application process, what can be expected, and to ask specific questions to faculty and graduate students. Please fill out the (short!) RSVP form below if you are interested in attending – there is a space to ask specific questions in the form in advance!

The form: https://forms.gle/jYh46M8zBK2xWnkbA?fbclid=IwAR3Sd4aUNvYqVglxi9jUGQvr8vXVLvM3GLNO4fIFKq-Mb0ZI-Avf4fVakKc

Happy new year!

Graduate Application Workshop

Hi everyone! For those of you applying to graduate schools with deadlines in January, as well as those who are perhaps thinking of applying to graduate schools in the future, we will be holding a graduate applications workshop on January 9 at 4pm in BA6183. There will be a faculty panel, as well as a graduate student panel, and an opportunity to ask questions about the application process and the like.

If you are interested in attending, please fill out the Google form below and include any questions you have for the panel.

Happy holidays!


Justin Martel: Energy vs. Mass Transport

Join us for our last talk before the new year, given by Justin Martel, a former graduate student at U of T. The talk will be Thursday, December 12th at 5:10pm in BA6180. Pizza will be served in the Graduate Lounge at 4:40pm.

Abstract: Is the distance from Toronto to Moscow today the same as the distance 2000 years ago? To the mathematician, ”Surely not!” when the distance is reckoned at 7500 kilometers ac- cording to the model globe in his office. But ”Distance” as- sumes entirely different dimensions when measured in terms of Energy-variables. A distance changes when the actual transit is taken into account. And how is it possible for the Hominid, capable of sustaining only an average of 75 Watts throughout an eight hour day, to transverse such great dis- tance?

This talk will describe, in simple terms, the principles of Optimal Transportation. We will focus on elementary physical models, energy, and Least Action Principles.
