I have written a number of papers on special functions associated with root systems, approximation theory, (complex and real) Paley-Wiener theory, and local spectral theory. My current focuses are on the interplay between topological dynamical systems and algebras of crossed product type, and, notably, also with my current PhD-students Marten Wortel and Miek Messerschmidt, on representation theory of algebras and groups in Banach lattices.
Since a number of years I have uploaded my papers to the arXiv, which is naturally more up to date than MathSciNet.
Summer School on Noncommutative Integration, Leiden, June 9 - 13, 2008.
Workshop Operator Structures and Dynamical Systems, Leiden, July 21 - 25, 2008 (satellite of 5 ECM). The proceedings appeared in 2009 in the Contemporary Mathematics series of the AMS.
The SIGMA Special Issue on Dunkl Operators and Related Topics, for which I was one of the guest editors, was completed in June 2009.
The Positivity VIII conference in 2013 will be in the Netherlands, organised as a joint venture between Leiden University and Delft University of Technology. I will chair the organisation committee.
I'll be teaching the national master course on functional analysis again, together with Andre Ran. It provides you with a broad basis in functional analysis beyond the introductory level. See the web page for more information. You need to have taken an introductory functional analysis course prior to this one. Measure and integration theory is not a formal prerequisite, but it does help.
I'll be teaching Analyse 4 (complex analysis), the home page of which can be found in Blackboard in due time, and Topics in Analysis, which will be on operators on the Hardy space H2, using the introductory book by Martinez-Avendano and Rosenthal on the subject. Prerequisites are introductory functional analysis (such as the Linear Analysis course), measure and integration theory, and complex analysis (Analyse 4 is more than sufficient). See also the functional analysis seminar below, which is a bit more demanding.
In Spring 2010 there will be a joint student/PhD-student/faculty seminar on commutative Banach algebras, based on Kaniuth's book "A course on commutative Banach algebras" (Springer, 2009). Students can participate for 6 EC. If you want to join, drop me a note (as several students already have!), and make sure you take the national master course in functional analysis first. Banach algebras are ubiquitous in analysis, and if you like abstract analysis, you will definitely like this subject.
I ran a number of seminars in the past period:
In the 2005 seminar for students we concentrated on spectral theory and operator algebras.
The 2006 seminar for students was about Banach space theory.
In the 2007 seminar for students the emphasis was on operator theory.
In 2007-2008 we covered most of the book by Albiac and Kalton on Banach space theory in a seminar for staff.
In 2008-2009 a staff seminar was held in Leiden about Meyer-Nieberg's book on Banach lattices; the twin seminar in Delft was on noncommutative probability.
