Dr. Ulrich Koschorke

Dear friends,

during the Rokhlin Memorial I was a guest at the Euler International Mathematical Institute.

I found the scientific atmosphere, the discussions and the lectures very stimulating. Also I liked eating in a nearby cafeteria and living in a nearby hotel with the other mathematicians. It helped to establish good contacts, both professional and human.

Thanks again for a very pleasant and productive time in St. Petersburg
