### Spring 2020

**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 (**Organizational meeting Aug. 26, 2019**)**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 Geometry and Physics****Organizers:**Jonathan Rosenberg (Math), Amin Gholampour (Math), Tristan Hubsch (Howard and UMD, Physics), Richard Wentworth (Math)**Meeting Time:**Thursdays at 3:30 PM, room MTH 1313 (**Organizational meeting Jan. 30, 2020**)**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. The topic for 2019-20 is symmetry-protected topological states of matter. Please see the web page or contact one of the organizers for more details.

**RIT on Quantum Information/Reading Group on Quantum Interactive Proofs****Organizer:**Carl Miller, Joint Center for Quantum Information and Computer Science (QuICS), Math, CS, and UMIACS**Meeting Time:**Wednesdays at 4:00 PM, Iribe 5105, starting Feb. 5, 2020**Description:**This group will study new results on computation with two quantum provers and a classical polynomial-time verifier. The recent paper “MIP*=RE” showed that, remarkably, the computational power of this setting is essentially unlimited. Our goal will be to deconstruct some of the tools used in “MIP*=RE” (and its predecessors) and to understand how the paper solves the longstanding Connes embedding problem.

**RIT on Number Theory****Organizers:**Jingen Chi and Thomas Haines**Meeting Time:**Fridays at 2:00 PM, (usually) Kirwan 3206, starting Feb. 7, 2020**Description:**This RIT will study "Projectivity of the Witt vector affine Grassmannian" by Bhatt and Scholze.

**RIT on Liquid Crystals - Modeling, Theory, and Numerics****Organizer:**Ricardo Nochetto and Lucas Bouck (Math)**Meeting Time:**Wednesdays 11:30 in Kirwan Hall 1310

**RIT on Weather, Chaos, and Data Assimilation**

**Organizers:**Kayo Ide (AOSC) and Brian Hunt (MATH).**Meeting Time:**Mondays at 2:00 in ATL 4301, starting**Sept. 23, 2019**.**Description:**We study prediction and estimation problems for nonlinear dynamical systems with main applications in (but not limited to) the atmosphere and the ocean. Emphasis is put on uncertainty quantification and reduction.

**RIT on Applied Optimization**

**Organizers:**Bruce Golden and Raghu Raghavan (Management Science)Van Munching Hall 3330H,**Meeting Time:****3-4 pm on Thursdays****Description:**This RIT will introduce AMSC students to some current topics in applied optimization (e.g., logistics). We will read and discuss several articles from the literature and then organize the class into small research teams. Each team will work on and "solve" one or two challenge problems provided by our colleagues in industry. Two of these colleagues received Ph.D.s from AMSC in the last 10 years. Sample problems: Logistics and network design for flying taxis, Delivering packages by trucks and drones, Designing meter reading vehicle routes using RFID, and Optimizing organ allocation geography to minimize disparities.**Topics Emphasized:**Combinatorial, network, and integer optimization (both exact and heuristic approaches).

**RIT on Applied Harmonic Analysis****Organizer:**Radu Balan**Meeting Time and Place:**MTH 1310 , Mondays 12:00pm-1:00pm**Organizational Meeting:****Mon, Sept. 9, 2019**- 12:00pm in MTH 1310
