### Spring 2017

**RITs ("Research Interaction Teams")** are informal groups designed to foster interaction between faculty, students, and postdocs, and to get students interested in current research. Most of them meet as informal seminars with active student participation (and in many cases, student organization as well). In addition to the RITs, there are several **student seminars** which are run by students for students.

**RIT on Applied Partial Differential Equations****Organizers:**Jacob Bedrossian, Maria Cameron, Sandra Cerrai, Manoussos Grillakis, Pierre-Emmanuel Jabin, Dave Levermore, Doron Levy, Matei Machedon, Dionisios Margetis, Antoine Mellet, Eitan Tadmor (lead organizers in bold)**Meeting Time:**3:00pm - 3:50pm Mondays**Location:**MTH 1311.**Description:**We will study mathematical aspects of applied partial differential equations. These might include well-posedness, long-time behavior, attractor dynamics, stability of coherent structures, asymptotic limits, and the relationship between chaos and stochasticity. However the best description is the list of talks given on the website.

**RIT on Statistics**

**Organizers:**Paul Smith, and Tingni Sun**Meeting Time:**Tuesdays 3:30-4:30, MTH 1313**Prerequisites:**a basic knowledge of statistics

**RIT on Analysis of Complex Networks****Organizers:**Maria Cameron and Kasso Okoudjou**Meeting Time:**Fridays at 2:00, MTH 1311, starting Sept. 2.

**RIT on Advanced Elementary Number Theory****Organizers:**Manjit Bhatia, Adam Lizzi, and Larry Washington**Meeting Time:**Fridays 3:00 PM in room MTH 1308, starting Jan. 27**Description:**The idea is to cover the fun stuff that is not usually included in Math 406. In other words, this will essentially be Math 407. We expect to meet once per week, with participants volunteering to lecture on various topics. We hope to keep at a level where someone who has studied number theory through quadratic reciprocity will be able to follow the lectures.

**RIT on Quantum Information****Organizers:**Brad Lackey, Carl Miller**When:**Mondays 4:15-5:15, with Organizational Meeting Sept. 12**Where:**CSS 3100A (Joint Center for Quantum Information and Computer Science)**Topics:**The RIT will focus on various mathematical aspects of quantum information, as it pertains to quantum foundations, quantum computing, and other topics in theoretical physics. No previous experience in quantum theory is required, however linear algebra and (discrete) probability is a must. To start the term we'll look at some basics in quantum foundations, primarily about generalized probability theories. After getting through the main constructions we'll decide if we want to study more advanced topic in quantum foundations or switch to a topic in quantum communication or information theory. Here are some papers to consider for the first part:- R. Clifton, J. Bub, and H. Halvorson, "Characterizing quantum theory in terms of information-theoretic constraints,"
*Found. Phys.***33**(2003); - C. Fuchs, "Quantum Mechanics as Quantum Information (and only a little more)," arXiv:quant-ph:0205039;
- P. Goyal, K.H. Knuth, and J. Skilling, "Origin of complex quantum amplitudes and Feynman's rules,"
*Phys. Rev. A***81**(2010); - L. Hardy, "Quantum theory from five reasonable axioms," arxiv:quant-ph:0101012;
- R.W. Spekkens, "In defense of the epistemic view of quantum states: a toy theory," arXiv:quant-ph:0401052;
- A. Wilce, "Formalism and interpretation in quantum theory,"
*Found. Phys.***40**(2010).

- R. Clifton, J. Bub, and H. Halvorson, "Characterizing quantum theory in terms of information-theoretic constraints,"

**RIT on Geometry and Physics****Organizers:**Jonathan Rosenberg (Math), Richard Wentworth (Math), Tristan Hubsch (Howard and UMD, Physics), and Chuck Doran (Alberta, Math, and UMD, Physics)**Meeting Time:**Thursdays at 3:30, room PHY 1117, starting Jan. 26.**Description:**This interdisciplinary RIT will aim to foster interactions between mathematicians and physicists on topics of mutual interest, such as supersymmetry, string theory, and gauge theory. Please see the web page or contact one of the organizers for more details. The topic for this semester is the big Clay/AMS book on D-branes and mirror symmetry.
