Professor Chuu-Lian Terng

Northeastern University

speaks on

Caustics and Submanifold Geometry

Abstract. The endpoint map of a submanifold $M$ in a complete Riemannian manifold $N$ is the restriction of the exponential map of $N$ to the normal bundle of $M$, and the singularities of the end point map are called focal points or caustics. In this talk, I will explain the relation between the structure of caustics and the topology and geometry of $M$ and $N$.

Tea. High tea will be served at 3:30pm in the Lounge.
Emmy's. Certain refreshments will be available at the Emmy's after the talk.
Host. Shunhui Zhu will be the host, anybody interested in having dinner with the speaker should contact Shunhui (Ext. 6-3678).
