August 10th-13th, 10am-4:30pm EDT, via Zoom. This website will be constantly evolving as we get closer to the conference, so feel free to drop by. (Make sure to hit refresh, wordpress often caches the page, so you get an old version.)

Along with most other conferences, both IWOTA (the International Workshop on Operator Theory and its Applications) and MTNS (the International Symposium on Mathematical Theory of Networks and Systems) have been postponed to Summer 2021.

To help fill this summer’s research and networking vacuum, we are launching the online workshop: 2TART Presents: Operator Theory with its Applications. As the name implies the workshop is affiliated with the 2TART Seminar Series and Conference, but has a broader based organizational board and mission, including the explicit promotion of work being done by our exceptional early career mathematicians.

The workshop will include more breaks and opportunities to talk about mathematics, featured talks by early career researchers, and facilitated or panel discussions during lunch. Participants are highly encouraged to actively participate by attending talks, asking questions and sharing ideas.
