Update

It has been a long time without any news. A small update:

  • IWI (the Department of Mathematics and Computer Science) has moved since September 1, 2007 to Bernoulliborg, our new building in the Zernike campus. You can find the new address at the homepage. If you are visiting from outside Groningen, take bus 11 or 15 from the train station and step off at Zernike. Bernoulliborg is the blue building in front of you.

On the road

From May 22 until June 2 I am visiting Université du Littoral at Dunkerque. Then, from June 16 until June 30 I will be in Montreal for the NATO ASI school on «Hamiltonian Dynamical Systems and Applications».

Hydrogen atom paper

The paper with Dmitrií Sadovskií and Boris Zhilinskií on «Classification of perturbations of the hydrogen atom by small static electric and magnetic fields» has been accepted for publication in Proceedings of the Royal Society A.

Cushman conference

Last week I was in Utrecht for the conference «Dynamics and Hamiltonian Systems» in honour of Richard Cushman for his 65th birthday. It was definitely one of the best conferences I have ever attended.

Edna Alford

Richard has retreated to Saskatchewan since December 2005 and seeing him is now a rare pleasure. But what made the conference so good, except for Richard’s presence of course, was the speakers and a very interesting collection of talks.

Farewell professor

I had the great luck of learning classical mechanics in a course taught by Nikos Voglis. He was then professor at the Department of Physics at the University of Athens and I followed his course as a second year student. He was an inspiring teacher and he commnunicated in the most skillful way the beauty and elegance of classical mechanics. So skillful, indeed, that after this course I knew that I wanted to work on classical mechanics from that moment on.

Docteur

Monsieur Efstathiou a exposé son travail en français, avec beaucoup d’aisance et de manière remarquablement claire. Ses réponses aux nombreuses questions, parfois difficiles, posées par les membres du jury, ont montré son souci d’aller au fond des choses, et sa grande autonomie, confirmée par les membres du jury qui le connaissent bien. Son travail, aussi intéressant pour son contenu mathématique que pour les applications physiques, pourrait aussi constituer une excellente thèse de mathématiques. Pour ces raisons, le jury a decidé à l’unanimité d’attribuer le titre de Docteur de l’Université du Littoral Côte d’Opale avec la mention «très honorable avec les félicitations du jury» à M. Konstantinos Efstathiou.
