Combinatorial Optimization Symposium JKL60

A DIAMANT Intercity Event



On December 19 2007 Jan Karel Lenstra will reach 60 years of age, which will be celebrated with a research seminar on combinatorial optimization on December 20. Jan Karel's scientific work on scheduling problems in the context of complexity theory has made the Netherlands a significant spot on the map of international research on Operations Research and Combinatorial Optimization. He is also playing a central role, nationally and internationally, in scientific organisation, currently being general director of the Centre for Mathematics and Computer Science (CWI) in Amsterdam. The seminar is a tribute to Jan Karel.

We are pleased to invite you to the seminar and give you the opportunity to congratulate Jan Karel at the subsequent reception. If you wish to join the free lunch, please indicate so by writing an e-mail to Kora Lemmens. Also, if you intend to come to the reception please indicate so in a message to Kora Lemmens, enabling us to get an idea of the number of people we may expect.

Seminar, lunch and reception are offered to you by generous support of the research school BETA, the Dutch Network on the Mathematics of Operations Research LNMB, the mathematics research cluster DIAMANT and the Department of Mathematics and Computer Science of the TU Eindhoven.

We hope to meet you at the 20th of December 2007 in Eindhoven.
