Dear all, Just a quick reminder regarding a talk by our visitor Prof. Chung-Shou Liao National Tsing Hua University, Taiwan, which might be of interest to you. The talk is at 15h, and it will be followed by an informal discussion with Chung-Shou (with coffee and some sweets) for whoever is interested in the coffee room on the 4th floor. Cheers, Elena and Evanthia
