### AWM Panel Discussion: The retention of women in mathematics

- Organizers:
- Ami Radunskya, Pomona College
- Christina Sormani, City University of New York
- Panelists:
- Julie Bergner, University of California, Riverside
- Andrea Bertozzi, University of California, Los Angeles
- Estela Gavosto, University of Kansas
- Douglas Haynes, University of California, Irvine
- Lisette de Pillis, Harvey Mudd College
- Chuu-Lian Terng, University of California, Irvine
- Moderators:
- Cheryl Geisler, Simon Fraser University

The AWM Panel at the 2013 Joint Mathematics Meetings will be on the retention of women professors in mathematics. This panel is being organized in response to an article in Science entitled “Survival Analysis of Faculty Retention in Science and Engineering by Gender”, in which it was reported that the survival rate for mathematicians was worse than any other field and the survival rate for women assistant professors in mathematics is only 4.45 years. Panelists from departments and universities which have successfully attracted and supported women through the tenure process will describe the methods that worked for them. Audience members are welcome to bring in questions and suggestions of their own. We particularly encourage young mathematicians to share their experiences with us.

The goal of the discussion will be to devise ways in which departments may work to retain their women assistant professors both by enticing them to stay and by providing the type of support that is needed for them to obtain tenure. The panel will have an online component located at https://sites.google.com/site/awmpanel2013/ . We encourage everyone to share their experiences and ask questions online.

### AWM Noether Lecture: A Hasse principle for quadratic forms over function fields

#### Raman Parimala, Emory University

The term ‘Hasse principle’ stands for the idea of finding integer solutions to equations by piecing together solutions modulo different prime powers. Solutions modulo prime powers lead to solutions in the completions of the field of rational numbers at *p*-adic valuations. A classical theorem of Hasse-Minkowski states that a quadratic form over rational numbers admits a nontrivial solution if it does over all *p*-adic completions and is indefinite over real numbers. There are more general theorems on the obstructions to the Hasse principle for the existence of rational points on homogeneous spaces under linear algebraic groups defined over number fields. We shall discuss formulations of the Hasse principle over function fields and some consequences for quadratic forms.
