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

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!

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!

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.

Hi everyone! Our next event will be talks from the 2019 Canadian Undergraduate Mathematics Conference (CUMC) by three students, Isabel Beach, Curtis Michael and Nikki Sigurdson. It will be Friday, October 25th, 2019 at 6:10pm, in BA 6183.
Pizza and pop will be provided!

Title: A Peek into Category Theory

Abstract: Have you ever heard about categories? What are they? What are they useful for?

We will start the following question: take two groups G and H and look at the set of homomorphisms between them. Does this set have a group structure? To answer this question, we will introduce some basic notions of category theory. We will reformulate our question in categorical terms and then see how categories help us solve it. Along the way, we’ll define what categories and functors are and look at examples. We’ll actually see that many mathematical objects we know are categories.
