## Dugald Macpherson’s birthday meeting

Still catching up on the backlog: last week I was in Edinburgh for a meeting at ICMS for Dugald Macpherson’s birthday. The ICMS has just moved to new premises at the top of the University of Edinburgh’s new Bayes Centre, … Continue reading

## 8th Cracow Conference on Graph Theory

How do two people share a cake? As everyone knows, one cuts and the other chooses. This does not assume that the two people value the cake in the same ways: maybe one loves cherries, and the other hates icing. … Continue reading

## Groups, geometries and representations

Here, more than a week late, are comments on the conference formally titled “Groups, Geometries and Representations, Oxford 2018”, actually a birthday conference for Dan Segal and Aner Shalev. I stayed in Balliol College’s new Jowett Walk Building, just around … Continue reading

## Linstat 2018

Or, to give the full title, International Conference on Trends and Perspectives in Linear Statistical Inference, with Celebration of Tadeusz Caliński’s 90th Birthday. The conference was in Będlewo Castle, once a private residence for a noble family which had more … Continue reading

## Pilsen, days 5 and 6

So the conference is over; but before I start a description of the last two days, let me pose a problem which might be an interesting small research topic for someone. As I have said, statisticians love symmetric real matrices. … Continue reading

## Pilsen, days 3 and 4

After the rush of the first two days, things quietened down a bit, so I can stop and look around me. The conference logo, and an explanation, is here. Norman Biggs, one of the pioneers of algebraic graph theory, speculated … Continue reading

## Pilsen, days 1 and 2

The conference on “Symmetry vs Regularity” in Pilsen has begun. I hesitate at trying to describe the talks, since the first day alone had 13 talks, and the second day 19, of lengths ranging from ten minutes to an hour, … Continue reading

## British Mathematical Colloquium: satellite meetings

The BMC was followed by three satellite meetings, on Semigroups and Applications, Geometric Group Theory, and Ergodic Theory. I had a lot of catching up and other jobs to do, and so was unable to go to more than a … Continue reading

## British Mathematical Colloquium, days 3 and 4

The day began with the plenary talk by Paul Seymour, whom I’ve known for longer than almost anyone else at the meeting. He explained that there are many different “ordering” relations on graphs; the two he considers most important are … Continue reading

## British Mathematical Colloquium, day 2

Things may be a bit briefer from now on. The first plenary talk was by Irit Dinur on the unique games conjecture. I think I understood roughly what this conjecture says, but what it has to do with games, unique … Continue reading
