Earlier this month I attended the 2013 Joint Mathematics Meetings, trading freezing Britain for sunny San Diego! This was the 119th annual meeting of the American Mathematical Society, the 96th of the Mathematical Association of America, my third trip to the US for a JMM, and the first at which I’ve given a talk. There …

I attended the 2013 Joint Mathematics Meetings in San Diego to present work at the AMS-SIAM Special Session on Mathematics of Computation: Algebra and Number Theory, II. Here are my slides, on Lehmer’s conjecture for Hermitian matrices over the Eisenstein and Gaussian integers.

These remarks started life as a series of short posts on Google+. But no-one uses Google+, so I’ve archived them here. I: you can make Voronoi diagrams using fine sand and blocks with holes drilled in. What’s a Voronoi diagram? In such an image, the plane is divided up into cells around sites, such that …

I spent last week in New Orleans for the Joint Mathematics Meetings 2011. I’d made a rather last minute booking after noticing a couple of sessions could be useful, and hadn’t quite grasped the scale of the event. I’d normally think of 200 mathematicians as a large gathering, but the JMM had over six thousand …

Conference and Outreach Activities for March/April.

View as: At The Diverse Faces of Arithmetic there were a pair of (early morning!) overview lectures for postgraduates. I’ve finally got around to typesetting my notes from the first, Tom Ward’s session on recurrence sequences, available as pdf via the above link. The topics included are divisibilty sequences and primitive divisors; linear recurrences; elliptic …

I shall be attending “The Diverse Faces of Arithmetic” in Norwich next week; taking a break from cyclotomic thoughts to revisit some topics I’ve mentioned here in the past, such as elliptic divisibility sequences.

There are now some videos available from the Beyond Part III / Young Researchers in Mathematics conference I attended earlier this year. Of particular note is David Spiegelhalter’s plenary lecture on probability and uncertainty. I summarised one of the ideas from that talk – the micromort – on Everything2, mentioning a comparison between the risks …

I’m back from the Fields Institute in Toronto, where I spoke at the above workshop, on my usual topic of cyclotomic and 4-cyclotomic matrices/graphs. During the talk I described my conjecture that a graph is maximal cyclotomic if-and-only if it’s 4-cyclotomic, and after an hour at the blackboards with James McKee I now have a …
