Thanks to Bob’s help, we now have a web page for the Sydney-UNSW Joint Colloquium at http://www.maths.usyd.edu.au/u/SemConf/JointColloquium/index.html It is also accessible through the drop-down menu from the school web page Research activities-->Seminars & Conferences-->Joint Colloquium You could find the list of earlier talks and some other information there. The most important thing is for all of us to consider it as a choice for visitors (or even yourself) to advertise the research fields.
