 Date:  Monday, September 18, 2017 Location:  3096 East Hall (4:00 PM to 5:00 PM) Title:  Extrapolation, a technique to estimate Abstract:   I will discuss a method to estimate a Banach space operator by embedding it in a family A_t of operators, $\sigma < t < \infty$, with suitable curvature properties. One can then estimate the norm of each A_t by bounds that hold in the limit as t tends to sigma and infinity, respectively.
