My mother died 2016-02-02 after a fairly short battle with cancer. Although aged nearly 82 she was very energetic and this was a big shock to all who knew her. It is a strange feeling when someone you thought would be around forever leaves so early. I have a memorial website to which anyone reading […]
I am running a survey (via Google Forms) on behalf of an international group of researchers and librarians interested in improving overall performance of the publication system in mathematics and other subjects. Its results will be made public later this year. We aim to get responses from a large and representative sample of the world […]
With summer scholarship student Jacky Lo, I have just submitted this paper to COMSOC 2016. This is the first time I have seriously looked at resource allocation in social choice. It was interesting and I may do more on this topic in future. Abstract: The problem of one-sided matching without money (also known as house […]
Today marks the end of an expensive and rewarding 5-week visit to Los Angeles. Most of it was vacation. We experienced some excellent museums (Petersen Automotive, Getty Center, La Brea Tar Pits) and the Santa Monica caught up with some old friends and colleagues, and spent a lot of time with many relatives. As expected, […]
Stephen Melczer and I have just posted a paper to arXiv.org: Asymptotics of lattice walks via analytic combinatorics in several variables. In my humble opinion this is a nontrivial advance in the area. It is a nice application of smooth and multiple point asymptotics in the framework developed by Robin Pemantle and me.
I can’t do better than point you to a short list of readings by a very prominent OA advocate, Peter Suber.
The Canadian general election will be held on 19 October. The most basic prediction method uses the full district (“riding”) vote information from the last election (in 2011), the current poll estimate for national level support for each party, and a model of changes in district votes. There are two main models used in predicting […]
In June and September I attended two contrasting political science conferences on the West Coast of the USA. PolNet 2015 was small (of the order of 100 attendees) and focused on political networks. APSA 2015 was huge (about 7000 attendees), covering all areas of the field, with many business meetings and other professional activities in […]

Networks in which the edges can be positive or negative occur in many applications (for example, in international relations, states may be allied or official enemies). A widely-used theory of “balance” predicts that networks should become more balanced over time. However there are no clearly agreed measures of partial balance. Samin Aref and I made […]
