Approximation and Harmonic Analysis

8-11 February 2005

at

The University of Auckland

Auckland, New Zealand

This is the third meeting organised by the New Zealand Approximation
Theory Group (following those in Christchurch 1999 and Westport 2002).
The topic Approximation and Harmonic Analysis will be interpreted
broadly. We plan to allocate lots of time without lectures for
informal interactions, including a conference trip to a Gulf Island
(probably Waiheke). Currently confirmed speakers include:

John Benedetto (Maryland), Carl de Boor (Wisconsin), Len Bos (Calgary),
Pete Casazza (Missouri), Xuan Duong (Sydney), Seng Luan Lee (Singapore),
David Levin (Tel Aviv), Detlef Mache(Bochum), Vilmos Totik (S. Florida/Szeged)

Accommodation

We expect most participants to stay at either O'Rourke Hall ($NZ 59
night incl breakfast) or Quest on Mount apartments ($NZ 118 studio,
$135 one room, $180 two rooms) which are located by the University (in
the downtown area).

About the location

Auckland, with roughly 1 million inhabitants, is the largest city in
New Zealand. It is built on an isthmus of 48 volcanoes (none currently
active) with a warm coastal climate and great beaches. Participants
might also be interested in the meetings ANZIAM 2005 (Napier, Jan 30
to Feb 3) and Geometry: Interactions with Algebra and Analysis
(Auckland, 14-18 Feb).

Registration

For now, expressions of interest can be made by writing to
conf...@math.canterbury.ac.nz. Later an electronic registration will
be set up.

Organising committee

* Rick Beatson (University of Canterbury)
* Qui Bui (University of Canterbury)
* Shayne Waldron (University of Auckland)
