This is the homepage for the UT Geometry and String Theory Seminar. At the organizational meeting we will flesh out the details of our plans for the semester. Below are some suggestions to get us started. There is a mailing list. To subscribe, send an email to [sympa@utlists.utexas.edu](mailto:sympa@utlists.utexas.edu) with subject<br/> "<code>subscribe math-gst <span style='color: brown'>Your Name</span></code>". At least for the Fall, the seminar will take place [online](https://utexas.zoom.us/j/99415038034). ## Fall 2021 Schedule ## {:r: scope="row"} Date|Speaker|Topic| ---:|:------|:----| {:r}8/25 | |Organizational Meeting| {:r}9/1 | | David Ben Zvi | {:r}9/8 | | David Ben Zvi | {:r}9/15 | | | {:r}9/22 | | | {:r}9/29 | | | {:r}10/6 | | | {:r}10/13| | | {:r}10/20| | | {:r}10/27| | | {:r}11/3 | | | {:r}11/10| | | {:r}11/17| | | {:r}12/1 | | | {: class="plaintable" style="text-align:center;" summary="Fall Schedule"} ## Spring 2022 Schedule ## {:r: scope="row"} Date|Speaker|Topic| ---:|:------|:----| {:r}1/19 | |Organizational Meeting| {:r}1/26 | | | {:r}2/2 | | | {:r}2/9 | | | {:r}2/16 | | | {:r}2/23 | | | {:r}3/2 | | | {:r}3/9 | | | {:r}3/23 | | | {:r}3/30 | | | {:r}4/6 | | | {:r}4/13 | | | {:r}4/20 | | | {:r}4/27 | | | {:r}5/4 | | | {: class="plaintable" style="text-align:center;" summary="Spring Schedule"} ## References ## ### Brane Quantization and Analytic Geometric Langlands ### * S.
