Seminar

From high oscillation to rapid approximation

Iserles, A (Cambridge)
Friday 30 March 2007, 09:00-09:45

Seminar Room 1, Newton Institute

Abstract

In this talk we address our recent work on the theory of modified Fourier expansions and their generalisation for the approximation of smooth functions in one and several variables. In particular, we debate rapid evaluation of expansion coefficients by means of Filon-like and Gauss--Turan-like quadrature techniques and various acceleration techniques.
