The list of plenary and sectional speakers for the International Congress of Mathematicians on 19-27 August, 2010 in Hyderabad, India is now available. Among the 171 sectional speakers are two Australian-based mathematicians, Norman Dancer (for the PDE section, at U. Sydney) and Brendan McKay (for the Combinatorics section, at ANU), as well as Australian-born Mark Kisin (for Number Theory, now at U. Chicago) and former UWA student Akshay Venkatesh (also for Number Theory, now at Stanford).
Further statistics on the speakers can be found at the AustMS blog. (Amusingly, the male/female split among the 171 sectional speakers is 147.5/23.5, due to some speaking slots being joint between two mathematicians.)
