A Circus?

The focus of this meeting on numerical mathematics was to let younger (and some older) researchers present their work: everyone was welcome to speak and listen.

The purpose was to exchange new ideas on numerical mathematics as understood in a broad sense. In particular we were interested in bringing together modeling, computation and analysis.

A cirkus?

The format followed the European Finite Element Fair:

On the day of the workshop, the workshop time was divided by the number of interested speakers into time slots; each talk was 10 minutes. Interested speakers, order drawn at random, were then given the opportunity to present their research. The idea was to present a new idea or result—not to present details of an entire research project. Time limits were strictly enforced!


The following 10-minute talks were presented at the Circus.
