| Description: | [DMS Topology & Geometry Seminar] Aritra Bhowmick -- Intersection of Cut and Focal Locus |
| Date: | Wednesday, Apr 29, 2026 |
| Time: | 2 p.m. - 3 p.m. |
| Details: | Rauch had made a conjecture that the cut and focal loci of a point always intersect in a simply connected manifold. Weinstein disproved this by showing the existence of a metric on any manifold (other than the 2-sphere) for which there is a point whose cut and focal loci are disjoint. In this talk we shall see how Weinstein's technique can be adapted to prove a similar result for submanifolds. Again, there will be many pictures to accompany! This is a joint work with T. Schick and S. Prasad. |
