3.00pm UCD L. Harris (Kentucky) Derivative estimates for

4.20 UCD C. Earle (Cornell & A dynamical approach to
Maths Sem Warwick) barycentric extension
Abstract for L. Harris: We begin with a discussion of inequalities between norms of multilinear mappings and homogeneous polynomials on various spaces. We then turn to analogues of the inequalities of Bernstein and Markov. Several open problems will be discussed.
Abstract for C. Earle: Unless it assigns measure 1/2 to two distinct points, every probability measure on the unit circle has a well defined "conformal barycenter" in the closed unit disk. Abikoff gave an iterative procedure - based on a generalization of the Denjoy-Woolf theorem - for computing it.
We shall explain that procedure and how it is used in joint work with Abikoff and Mitra both to give a new definition of the barycenter and to extend self-maps of the unit circle to self-maps of the closed unit disc, generalizing previous work of Douady and Earle.

4.00pm TCD L. Harris (Kentucky) Fixed points of Holomor-
2.6 phic Mappings on a
Banach Space
Abstract: This talk gives a basic introduction to infinite dimensional holomorphic functions and associated fixed point theorems. The numerical range of holomorphic functions is introduced and conditions on it are given for the existence of fixed points. These results are applied to give a quantitative version of the inverse function theorem.
