| Description: | [DMS seminar] Dr. Suparna Sen (Indian Statistical Institute, Calcutta) -- Roe-Strichartz Theorem on some two step nilpotent Lie Groups |
| Date: | Wednesday, Feb 19, 2014 |
| Time: | 3 p.m. - 7 p.m. |
| Venue: | Class Room 2, JC Bose |
| Details: | Generalizing a result of J. Roe for functions on the real line, Strichartz proved that if a doubly infinite sequence of uniformly bounded functions $\{f_k\}_{k \in \mathbb{Z}}$ on $\mathbb{R}^n$ satisfy $f_{k+1} = \Delta f_k$ for each $k$ where $\Delta$ is the Laplacian on $\mathbb{R}^n,$ then $\Delta f_0 = - f_0.$ He also proved a similar result on Heisenberg group. We give a generalization of this result to some two step nilpotent Lie groups. |
