University of Toronto Math Department Colloquium Videos Winter 2013

The Department of Mathematics at the University of Toronto has recently deployed a new granular content management system called KBasix for sharing files and web content. We’ve deployed and enriched a KBasix system to create a video upload-transcode-stream service for the videos of seminars and colloquia that take place in our department. I am grateful to Pamela Brittain, Marco de la Cruz-Heredia, Emile LeBlanc and Habiba Mohtadi for their efforts at making it possible for the world to tune into our colloquium stream!

Ubiquity of Mathematics: Charles Fefferman

This is Episode 1 of a 5 part video series entitled Ubiquity of Mathematics. I am grateful to the Department of Mathematics, the Fields Institute, Richard Cerezo, and Andrea MacLeod for making this project happen. I also thankful the mathematicians interviewed for this series: Spyros Alexakis Ingrid Daubechies Charles Fefferman Adrian Nachman Luis Seco The other episodes will appear shortly. Here is the transcript and here is the video of the interview with Charles Fefferman:

Zaher Hani Seminar: A Continuum Large Box Limit for the Cubic Nonlinear Schrödinger Equation

Analysis & Applied Math Seminar 2013-03-21 Speaker: Zaher Hani Institution: New York University Abstract: Inspired by the general paradigm of weak turbulence theory, we consider the 2D cubic nonlinear Schrödinger equation on a box of size L with periodic boundary conditions. In an appropriate “large box regime” (L very large), we derive a continuum equation on ℝ2 that governs the dynamics of the discrete frequency modes over nonlinear time scales. This equation turns out to satisfy many surprising symmetries and conservation laws, as well as several families of explicit solutions.

Larry Guth Colloquium: Unexpected Applications of Polynomials in Combinatorics

My former colleague Larry Guth (now at MIT) visited us recently and gave a beautiful colloquium talk. The Department has recently deployed a video streaming service so we are able to share Larry’s talk with the world. We look forward to sharing other videos in the future.   Here is the video: Your browser does not support the <video> tag.     Unexpected applications of polynomials in combinatorics by Larry Guth | MIT Time: 16:10 (Wednesday, Jan.

Canada is Retreating from Investment in Science and Engineering

  (The following is a slightly edited version of an invited post appearing on The Inside Agenda Blog on TVO’s web space.) Canada retreats from Science Canada is retreating from investment in science and engineering. Public letters (by 10 prominent physicists, 336 mathematicians, 49 leading researchers) have signaled alarms at changes to the NSERC Discovery Grants Program and the elimination of the Major Resources Support (MRS) and Research Tools and Instruments (RTI) programs.

On Today's NSERC Contact Newsletter Item Regarding Postdocs

I received today the September 2012 Contact Newsletter (volume 36, number 4) from NSERC via email. The fourth item in the newsletter reads: Postdoctoral Fellowships - no change to number of awards Over the last ten years, the volume of applications to the NSERC PDF Program has doubled to about 1,300, impacting the workload of volunteer selection committee members. A change to the eligibility rules for the Postdoctoral Fellowships (PDF) Program was made to ensure that applicants’ and reviewers’ time was used productively.

Canada Restricts Athlete Participation to One Olympic Games per Lifetime

The (false) headline conveys the sporting analog of NSERC’s new policy on Postdoctoral Fellowship Competitions: Effective as of the 2013 competition, you can only apply once to the NSERC Postdoctoral Fellowships (PDF) Program; however, applicants whose first PDF application was submitted prior to the 2013 competition may submit a second application provided they are within the eligibility window. What’s going on? Why would Canada choose to limit the pool of participants competing for advanced training opportunities in science and engineering?
