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 2013 Schedule## {:r: scope="row"} Date|Speaker|Topic| ---:|:------|:---- {:r}8/28 |The Organizers|Organizational Meeting {:r}9/11 | ??? | ??? {:r}9/18 | ??? |??? {:r}9/15 | ??? | ??? {:r}9/25 | ??? | ??? {:r}10/2 | ??? | ??? {:r}10/9 | ??? | ??? {:r}10/16| ??? | ??? {:r}10/23| ??? | ??? {:r}10/30| ??? | ??? {:r}11/6 | ??? | ??? {:r}11/13| ??? | ??? {:r}11/20| ??? | ??? {:r}12/4 | ??? | ??? {: class="plaintable" style="text-align:center;" summary="Fall Schedule"} ###References### ####The 6D (2,0) Theory#### * D.
