**Number Theory**
**Title:** Some number theory associated to automorphic forms on SL_2

**Speaker:** Nike Vatsal

**Speaker Info:** University of British Columbia

**Brief Description:**

**Special Note**:

**Abstract:**

We'll explain how some familiar questions from number theory have a simple interpretation in terms of automorphic forms on SL_2, rather than the usual GL_2, and also prove a converse theorem for forms on SL_2.
