As part of the cooperation within the Stieltjes Institute the analysis research groups of the University of Leiden, Free University Amsterdam, University of Amsterdam, Delft University of Technology, Eindhoven University of Technology, Erasmus University (EUR), and the Center for Mathematics and Computer Science Amsterdam, organize a joint analysis colloquium.

In 2002 the colloquium was organized by Joost Hulshof and Andre Ran at the Free University of Amsterdam. The meetings took place on April 8 and November 28 & 29 (Farewell symposium for Rien Kaashoek).
