Draft paper – On the uncoloured quantum link invariants from U_{q}(osp(1|2n)) and U_{-q}(so(2n+1))

November 27, 2006

Last week I finished a draft of a small paper the idea for which came to me at ICM in Madrid in August, possibly while talking to Nathan Geer after my talk. Pretty soon afterwards, I wrote down the beginnings of the idea at this post. It’s taken a fair bit of work to get it to this draft stage. I’m happy to e-mail a pdf of the draft paper to whomever requests it.

Essentially, the paper says that the quantum link invariants from the algebras mentioned in the title, obtained by colouring each component of the link with the respective irreducible (2n+1)-dimensional representations, are related by a change of variables. The thing is, it may not necessarily be possible to directly convert an invariant from one quantum algebra to the invariant from the other quantum algebra, as you have to actually look at the parent link invariant from the Birman-Wenzl-Murakami algebra in two indeterminates (r and s).

Etiquette at a music concert

November 12, 2006

This post is just a personal observation about etiquette at music concerts. Last night, Mr T and I went to the Kylie concert at the Sydney Entertainment centre and I really enjoyed it – I enjoyed the energy, lights and dance routines and sang along to a few songs. Read the rest of this entry »

A vote-swap web-site for the Democrats/Greens in the US?

November 10, 2006

Something that struck me about the recent US mid-term elections was the closeness of many results – indeed, to voters in a preferential system it would seem that different results may well have emerged in the Virginia senate election if a preferential system was in force. Of course, there’s the famous case of the probable effect of Nader running in the 2000 Presidential election, taking votes from Gore.

Given the closeness of many races, I wonder if it would be electorally strategic for the Democratic Party to set up a vote-swap web-site or other system, where Green voters in a close race (say were the opinion polls give the different at 10% or less) could swap their votes with Democrat voters in races where the Democrats are thought to be romping it in (say in the NY senate race). A similar system operates in the UK for Labour and Liberal Democrats.

Potential federal electoral impacts of increased petrol prices and higher interest rates

November 10, 2006

Possibly one of the most greatest influences on the federal electoral climate at the moment are the combined effects of increased interest rates and changing petrol prices. While petrol prices have recently declined, they are still higher than they generally were before 2001 and it looks as if they’ll stay at a higher level for the forseeable future. According to today’s Australian, interest rates have climbed 4 times since the 2004 federal election and it doesn’t look as if they’ll decline in the foreseeable future.

Back from blogging holiday!

November 2, 2006

Yes, I’m back from my blogging holiday, although I’m going to focus mostly on CDAs (career development activities). I’ll write posts when the urge strikes. I have been writing comments on other blogs – I can’t resist!

I’m starting to learn statistics and learn about some of its applications. It’s interesting.

On Saturday, we’re off to the Gold Coast for a couple of days (a birthday holiday) and on Sunday we’re driving up to Brisbane to have a birthday lunch for mum (her birthday is two days after mine). I’m back at work on Thursday.
