Prof. Alice Chang to Visit Purdue, November 19, 2009

The Department of Mathematics will hold its third annual Women in Mathematics Day on Thursday, November 19, 2009. As in the past, the spirit of this event is to provide an opportunity for women members of the Mathematics Department (faculty and students) to interact with each other and with a prominent female mathematician who delivers the scientific highlight of the day, the Jean E. Rubin Memorial Lecture, to the entire Mathematics Department in the afternoon. This year, Professor Sun-Yung Alice Chang (Princeton University) will be the lecturer. The event is generously sponsored by Chris Sahley, through the Purdue's program "Women in Academia", and by the Department of Mathematics.

The notion of Q-curvature was introduced by Paneitz-Branson in the early 1980s as a direct generalization of the Gaussian curvature on a compact surface. The notion was originally defi ned only for manifolds of dimension four. In recent years, there have been intensive efforts to study the subject mainly due to its conformal invariant property and its connection to some geometric invariants in the asymptotic hyperbolic, conformally compact Einstein manifolds. In this talk, I will give a brief survey of the subject with emphasis on applications to problems in conformal geometry.
