Non-Local Operators - Ikemefuna Agbanusi

Wednesday, May 22nd, 2019

Time: 1:30 p.m.  Place: Jeffery Hall 101

Speaker: Ikemefuna Agbanusi (Colgate University / Colorado College)

Title: Non-Local Operators Everywhere

Abstract: My goal in this talk is to give another approach---along with examples, characterizations and refinements of local and non-local operators. Very loosely speaking, non-local operators are necessary if one wishes to "albegraically complete" the local ones and my goal in this talk is to explain why and show also that pretty much all the "interesting" operators are non-local.

Nonlocal problems in PDEs and geometry

May 20-24, 2019

Prof. Eleonora Cinti (Università di Bologna, Italy) will teach a 5-day mini-course aimed at graduate students and junior researchers at the intersection of Analysis and Geometry.

Dr. Cinti earned her Ph.D in 2010 and since then has worked at the Max Planck Institute in Leipzig, the Weierstrass Institute in Berlin, and various Italian universities (Pavia, Bologna, Torino). Eleonora Cinti's research focuses on nonlocal partial differential equations, geometric measure theory, and calculus of variations.


The mini-course will be structured as follows:

  • Lecture 1 (Monday, May 20): Preliminaries: basic facts about the Laplacian and harmonic functions.
  • Lecture 2 (Tuesday, May 21): The fractional Laplacians: motivations and properties.
  • Problem Session (Wednesday, May 22).
  • Lecture 3 (Thursday, May 23): $s$-Harmonic functions and the Caffarelli-Silvestre extension theorem.
  • Lecture 4 (Friday, May 24): Geometry meets PDEs, a nonlocal phase transition model and nonlocal minimal surfaces.

All Girls Math Team Shines on the International Stage

EGMO Team Canada 2019

EGMO Team Canada 2019

May 8th, 2019

The Canadian Mathematical Society is pleased to announce that its second team to compete in the European Girls Mathematical Olympiad (EGMO) has returned from Ukraine, medals in hand. The Canadian EGMO Team earned two Bronze Medals and two Honourable Mentions.

The EGMO competition got started in 2012 when it was first written in Cambridge, UK and has since grown to include more than 50 countries. Participation in the EGMO is by invitation only. Each student competes individually to solve six questions in a competition lasting two days, four and a half hours each day. The Girls Math Team Canada was selected largely based on the results of the 2018 Canadian Open Mathematics Challenge (COMC) written in November, as well as a Team Selection Test that was sent to the top 15 girls from the 2018 COMC.

Community Collaborations – Women in Mathematics

April 22nd, 2019

Congratulations to Stefanie, who was awarded the prize in the Community Collaborations category.

Here is Stefanie’s commentary:  Mathematical thinking is about finding patterns and structure. As a woman in the mathematics PhD program, I hope to inspire young women to follow their passion and find beauty in mathematics. At Queen’s we offer the MathQuest camp for high school girls. As captured in the photo, I am brainstorming ways to teach game theory and linear algebra. This is also a part of my research with Dr. Peter Taylor, where we work with teachers across Ontario looking for innovative ways to incorporate mathematical thinking in education. We hope to change the math curriculum by making it a more engaging, positive and memorable experience.

The 2019 Art of Research photo contest received more than 100 submissions from Queen’s faculty, staff, students, and alumni, who took up the challenge of capturing their research programs in engaging and thought-provoking ways.
