Dear Allan,

Hope you are in good shape.

After having discussed with Andrzej and Pawel, and knowing very well Dominique Foata, Jean-Yves Thibon and Alain Lascoux, I think it would be a great idea if you did a little "after dinner speech" in Karol's Honour.
Emerging from conversations with different people, some ideas : 
- recall that it's Karol's 60th birthday
- he had the idea of this colloquium
- he is one of the (tirelessly) most involved personality for the interdisciplinarity (math-physics-computer sciences) and cross-fertilization of the polish and french communities (after all have we not been recently together to celebrate the 50th birthday of it ?)
- he (up to me) has a lot of fresh and creative ideas for this particular blend of the "group of five" which mixes : analysis, algebra, graph theory, physics, data structures etc...
- and, last but not least, music, transcriptions and piano

of course feel free to amend this list.

What do you think of this idea ? we are impatiently waiting (with Pawel and Andrzej), your answer.

Best regards
Gérard
