Title: Poincare type inequality and the Arveson-Douglas Conjecture

Abstract: The Poincare inequality says that the Lp norm of a function is controlled by its gradient. Boas and Straube improved that inequality by adding a weight function on the gradient. By applying this inequality on the Hardy and Bergman spaces on bounded strongly pseudoconvex domains with smooth boundary, we show that the Hardy norm of a function is equivalent to a weighted Bergman norm of its gradient. This allows us to apply existing techniques for submodules of the Bergman module, and obtain essential normality for principal submodules of the Hardy module.

Title: Recovering parameters in mathematical models

Abstract: Ordinary differential equation (ODE) models are very common in applications. This talk addresses, for ODE models that are linear, the problem of when parameters can be recovered from data. I will highlight how techniques from differential algebra reduce the problem to one that can be solved using linear algebra and combinatorics. I will also highlight some examples coming from biology. No background will be assumed.
