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. ##Fall 2017 Schedule## {:r: scope="row"} Date|Speaker|Topic| ---:|:------|:----| {:r}8/30 | |Organizational Meeting| {:r}9/6 | |Introduction + [Komargodski video](http://scgp.stonybrook.edu/video_portal/video.php?id=3271) (pt 1)| {:r}9/13 | |[Komargodski video](http://scgp.stonybrook.edu/video_portal/video.php?id=3271) (pt 2) | {:r}9/20 |Ivan Tulli | anomalies, part 1 | {:r}9/27 |Sebastian Schulz | anomalies, part 2 | {:r}10/4 |Sebastian Schulz | anomalies, part 4 | {:r}10/11|Arun Debray | anomalies in discrete symmetries | {:r}10/18|Arun Debray | anomalies in discrete symmetries, 2 | {:r}10/25|Fei Yan | Generalized Global Symmetries, Part I| {:r}11/1 |Philip Argyres | | {:r}11/8|Fei & Ravi | Generalized Global Symmetries, Part II | {:r}11/15|Ravi Mohan | Generalized Global Symmetries, Part III | {:r}11/29|Clay Cordova| | {:r}12/6 | Ali Shehper |Comments on global symmetries, anomalies and dualities in (2+1) dimensions | {: class="plaintable" style="text-align:center;" summary="Fall Schedule"} ###References### #### (Higher) Symmetries, Anomaly-Matching and Phases of QCD * A.
