as you probably already noticed, there is a highly interesting talk scheduled in two weeks at the time of our seminar. For this reason, we will have no seminar (the talks will be rescheduled) -- and I hope to see most of you at Karlov where Cedric Villani will be speaking about The gas, stars and eternity. 

(For too quick readers: this is about April 13. 

Next week, April 6, is no seminar because of spring school.)
