Past Events | RTG Dynamics: Classical, Modern and Quantum

Ergodic Method in Group Theorey 2025 was supported by the RTG “Dynamics: Classical, Modern, and Quantum”. Its Summer School was held May 26-May 30, 2025. All events were held on Northwestern University’s Evanston campus.

Summer School on Arithmetic and Random Groups was supported by the RTG “Dynamics: Classical, Modern, and Quantum”. Its Summer School was held May 19-May 23, 2025. All events were held on Northwestern University’s Evanston campus.

The spring 2025 Midwest Dynamical Systems conference took place April 25-27, 2025 at Northwestern University. The conference was partially supported by the RTG “Dynamics: Classical, Modern, and Quantum” as well as the conference grant DMS-2230827.

NU Trends in Ergodic Theory 2024 was supported by the RTG “Dynamics: Classical, Modern, and Quantum”. Its Summer School was held July 29-August 2, 2024 and its conference was held August 5-9, 2024. All events were held on Northwestern University’s Evanston campus. The Summer School introduced early graduate students to modern ergodic theory and prepares them for the conference NU Trends in Ergodic Theory. The school covered several aspects of modern ergodic theory at a level suitable for those with a background in analysis. The conference brought together researchers working on many aspects of ergodic theory, aimed to encourage interactions between young researchers and research leaders, and communicated new techniques to the community.

Microlocal Analysis and Quantum Dynamics was held on NU’s Evanston campus June 17-21, 2024 (summer school) and June 24-28, 2024 (conference). It focused on recent developments in applications of the tools of semiclassical microlocal analysis, with a focus on quantum dynamics. Areas of applications included quantum chaos, scattering resonances and Ruelle resonances, and solid state physics. The conference also honored the mathematics and legacy of Steve Zelditch.

Summer School 2023 on Dynamical Systems took place June 20–June 30, 2023 on the Evanston campus of Northwestern University. It featured preparatory courses (including courses appropriate for advanced undergraduates) as well as advanced courses. Mini-courses were presented by Alena Erchenko, Mikolaj Fraczyk, Nicholas Miller, Amir Mohammadi, Kurt Vinhage, and Daren Wei. The Summer School 2023 organizers were Nir Avni, Aaron Brown, Osama Khalil, Bryna Kra, and Homin Lee. It was funded primarily through the following NSF grants: DMS-2136217 (RTG: Dynamics: Classical, Modern, and Quantum) and DMS-2020013 (CAREER: Rigidity of Group Actions on Manifolds). Additionally funding was provided by Northwestern University’s Department of Mathematics. REU Summer 2023 took place June 20–Aug 11, 2023 on the Northwestern University’s Evanston campus. Mentors for the summer 2023 REU included NU Mathematics faculty members Nir Avni, Aaron Brown, Keith Burns, Solly Coles, Tsachik Gelander, Aaron Peterson, Jeff Xia. This program was made possible by the National Science Foundation and was funded by the RTG Dynamics: Classical, Modern, and Quantum

This was the first post-pandemic installment of a (usually) biennial meeting on microlocal analysis and quantum dynamics. The meeting was be partly supported by Northwestern’s NSF RTG in Dynamics. MMMM 2023 was held May 20-21, 2023. Its organizers were Kiril Datchev (Purdue University), Antônio Sá Barreto (Purdue University), David Sher (DePaul University), and Jared Wunsch (Northwestern University)

The UIC chapter of Dynamics ran a Chicago Action Now rotating seminar (Groups and Dynamics Day) on April 1, 2023 at UIC. Speakers included Miklos Abert (Renyi Institute), Kaitlyn Loyd (Northwestern University), Mikolaj Fraczyk (University of Chicago), Alena Erchenko (University of Chicago), and Barak Weiss (Tel Aviv University)

NU Mathematics faculty member, Prof. Bryna Kra, presented her talk, “The Legacy of Erdős: Dynamics of Numbers” on Oct. 27, 2022.
Abstract: Paul Erdős wrote almost 1500 papers with hundreds of collaborators and one measure of his influence is captured by the Erdős number capturing collaborations among mathematicians. He was well known for posing problems in combinatorics and number theory, offering monetary prizes for the solution of many questions. Some of these conjectures have had great influence in dynamical systems, creating connections with seemingly unrelated fields. This talk will cover those developments on uncovering hidden structures in large sets of integers, including the solution to some conjectures of Erdős this year and some problems that are still left open

This Dynamics Day mini-conference was hosted via Zoom on October, 11 2022. Presenters were Van Cyr, Osama Khalil, Solly Coles, and Yanglong Hao.
