| Description: | [DMS Seminar] Dr. Bata Krishna Das (IIT Bombay) -- Isometric dilations of operator tuples and von Neumann inequality |
| Date: | Wednesday, Mar 29, 2017 |
| Time: | 2 p.m. - 3 p.m. |
| Venue: | G09, Lecture Hall Complex |
| Details: | In this talk we will describe a method for finding isometric dilation of an $n$-tuple $(n\ge 3)$ of commuting contractions under some positivity assumption. This in turn provides that the von-Neumann inequality for such an $n$-tuple holds on a variety of the polydisc $\mathbb{D}^n$. If time permits, we will find a larger class of commuting operator triples having isometric dilations and discuss their von Neumann inequality. |
