York Geometry, Analysis and Number Theory Seminar, Spring Term 2001
Final programme.
Unless otherwise indicated, talks are in Vanbrugh College, room V/131, at
11:30 every (well, almost every!) Wednesday morning during term. Coffee
beforehand in the same room at 11:00. Everybody welcome!
- Wednesday 17th January 2001
- Speaker: Sanju Velani (QMW)
- Title: Simultaneously badly approximable numbers
- Wednesday 31st January 2001: algebra seminar
- Speaker: Dr Benjamin Steinberg (University of Porto)
- Title: Topological spaces for inverse semigroups
- Dr Steinberg is also speaking in
the departmental seminar series. Please contact
John Fountain for further information.
- Wednesday 14th February 2001
- Speaker: Simon Eveson
- Title: Norms of Iterates of Volterra Operators (V)
- Abstract: Let V^n represent the Riemann-Liouville fractional
integration operator, which is a bounded operator on L^p(0,1)
for any p. When p=2, the asymptotic behaviour of ||V^n|| as
n tends to infinity was shown by Donald Kershaw in 1999 to be
1/(2n!). This talk is principally about the asymptotics of
||V^n|| on L^p, but also contains some new results on the Hilbert
space case.
- Wednesday 28th February 2001
- Speaker: Maurice Dodson
- Title: The logical structure of sampling theory and Fourier analysis.
- Wednesday 7th March 2001
- Speaker: Ian McIntosh
- Title: Minimal and CMC surfaces in 3-dimensional geometries
- Abstract: There are some slick and surprising formulas for the
construction of minimal and constant mean curvature (soap film
and soap bubble) surfaces in 3-dimensional space forms (spheres,
hyperbolic spaces and Euclidean spaces). The aim is to explain how
these all arise from one approach which uses the loop group for
SL_2(C). This approach has been encoded numerically and there is a
strong possibility that many pictures of examples will be shown.
