## All kinds of mathematics: workshop and conclusion

The final day of the conference was devoted to a satellite workshop on “Symmetry in finite and infinite structures”. The morning was a solo performance by Laci Babai, in which he explained in detail his quasi-polynomial algorithm for graph isomorphism. … Continue reading

## All kinds of mathematics, 4

The fourth day began with a talk by László Babai on his quasi-polynomial algorithm for graph isomorphism. Two longer and more detailed accounts were scheduled for the workshop; this talk gave the context, and an important lemma which underlies the … Continue reading

## All kinds of mathematics, 3

Wednesday morning’s first speaker was Bob Gray, who told us about his quest, with Igor Dolinka, on a semigroup analogue for Philip Hall’s countable universal homogeneous locally finite group. He started with a clear introduction to Hall’s group. For semigroups, … Continue reading

## All kinds of mathematics, 1

There is far too much, and far too diverse, mathematics going on here for me to describe all or even most of it. Nine plenary lectures on the first day! The talks are being live streamed at https://videocast.fccn.pt/live/idprovider_uab/kinds_mathematics_remind, though the … Continue reading

## In Lisbon

Currently in Lisbon, as the picture suggests. Work last week; something rather more extraordinary coming up …

## BCC26, 2

The first lecture on Thursday was by Benny Sudakov, on robustness of graph properties. For purposes of exposition, he had decided to focus on one particular property, that of being Hamiltonian. Dirac’s famous theorem tells us that a graph on … Continue reading
