APPLIED ALGEBRA AND ANALYSIS ONLINE SEMINAR


Applied Algebra and Analysis Online Seminar (AAA) aims at bringing together researchers that develop algebraic and analytic tools to tackle problems coming from different areas of science and engineering.

Date: every second Thursday 17:00-18:00 (CEST) at https://webconf.tu-bs.de/dir-grt-gft.

The AAA in-person meeting will take place on Friday, July 1, at TU Braunschweig.
