This year, the Analysis and Operator Theory Seminar hosted mathematicians from around the world, generously supported by the Mathematics Research Institute at OSU. The seminar welcomed speakers from every career level, including early career researchers (postdocs and graduate students) to world-renowned experts. Talks were conducted both in-person and virtually, with visitors traveling from as far as Belgium and the Czech Republic and virtual speakers from places like Germany and South Africa. The seminar also included speakers from OSU, fostering the development and deepening of collaborations within the department.
The variety of topics covered during the talks represented the wide-ranging interests of the seminar participants within the department. Topics included properties of differential operators, delay equations, Sobolev embeddings, integral inequalities, and asymptotic analysis, to name just a few. The talks even included an introductory lecture on general relativity and blackholes by Georgios Mavrogiannis from Rutgers University.
A highlight of the seminar this year was hosting international visitors for in-person talks and continued collaboration with members of the department. Zdeněk Mihula (a former Fulbright visitor at OSU) visited from the Czech Technical University to discuss some quantitative aspects of noncompact Sobolev embeddings. Additionally, Mateusz Piorkowski from KU Leuven presented his recent work on the Riemann-Hilbert analysis of the initial value problem for the KdV equation with steplike initial data. Mateusz also discussed the doubly periodic tiling model of the Aztec diamond in a joint seminar talk with the Combinatorics and Probability Seminar.
