Organizers: Richard Wentworth (Math), Tristan Hubsch (Physics, Howard Univ.), Jonathan Rosenberg (Math), Amin Gholampour (Math, on leave)
Other Faculty Participants: Joel Cohen (Math, on leave), Paul Green (Math, emeritus)
When: Thursdays @ 3:30pm-4:30pm
Where: PHY 1117 (This is the Center for Particle & String Theory, located in what used to be the physics chair's office in the Toll Physics Building adjacent to the Mathematics department.)
This interdisciplinary RIT will aim to foster interactions between mathematicians and physicists on topics of mutual interest. It will roughly follow the example of a similar RIT from 2010-2011 and from the last three years. The topic for 2016-17 was mirror symmetry.
It is not assumed that participants already be knowledgeable in both math and physics, just in some aspect of one or the other. Relevant math topics are differential geometry, representation theory, algebraic topology, and algebraic geometry. Relevant physics topics are classical and quantum field theories, and supersymmetry.
The organization meeting for Fall 2017 is scheduled for September 7th. Students (advanced undergraduates or graduate students) who want to participate can get credit as MATH 489 (undergrad) or 689 (graduate) if they wish, by contacting the organizers.
We have a wiki where participants can exchange comments and revise notes. Contact the math/physics computer helpdesk if you need a login id and password.
Topics from previous years:
The topic for fall 2017 is topological states of matter. In no particular order, here is a list of references:
The topic for spring 2018 is generalized geometry and its applications to physics (especially supersymmetry and string theory). We will begin with the first reference listed, Hitchin's notes. Here is a short list of basic references:
Organizers: Ricardo Nochetto, Wujun Zhang
When: Wednesdays @ 5pm-6pm, starting the first week of February
Where: room TBA
Subtitle: PDE theory and numerical analysis
Fully nonlinear second order elliptic PDEs arise naturally from differential geometry, stochastic control theory, optimal transport and other fields in science and engineering. In this RIT, we will discuss the concept of viscosity solutions and regularity theory of these PDEs. Some possible topics include:
In contrast to an extensive PDE literature, the numerical approximation reduces to a few papers. We would like to discuss some criteria for designing convergent numerical methods and some tools developed recently which are useful to obtain rates of convergence. Some possible topics include:
Organizers: Niranjan Ramachandran, Dio Margetis, and Leo Koralov
When: Wednesday @ 3:15pm, Tea 2:45pm - 3:15 pm in room 3201
Where: Math 3206
From time to time special colloquia are held on other days, sometimes as part of conferences.
Other special colloquia are the Aziz Lectures and Avron Douglis Memorial Lectures.
Location: Math 3206
Day: Wednesday (with occasional talks Friday)
Time: 3:15pm
Tea: 2:45pm in 3201
Organizers: Giovanni Forni, Harry Tamvakis, Konstantina Trivisa
