Alexander Konovalov and Michael Torpey recently taught at two Software Carpentry workshops. The first one was a workshop for University of St Andrews researchers supported by CAPOD, and the second one was for the the EPSRC Centre for Doctoral Training in Critical Resource Catalysis (CRITICAT)
The next major release of GAP, version 4.10.0, has been announced in November 2018. You can find further information and links to the release announcement and an overview of new features in this post on the CoDiMa website.
The next CIRCA Lunchtime Seminar will be on Thursday 15th February in Maths Lecture Theatre C at 1pm. Ian Gent and Markus Pfeiffer will be speaking.
There will be a seminar on Wednesday February 7th, 2018 at 1pm in Lecture Theatre D: Peter Cameron will speak on Reed–Muller codes and Thomas’ conjecture.
Abstract: A countable first-order structure is countably categorical if its automorphism group has only finitely many orbits on n-tuples of points of the structure for all n. (Homogeneous structures over finite relational languages provide examples.) For countably categorical structures, we can regard a reduct of the structure as a closed overgroup of its automorphism group. Simon Thomas showed that the famous countable random graph has just five reducts, and conjectured that any countable homogeneous structure has only finitely many reducts. Many special cases have been worked out but there is no sign of a general proof yet. In order to test the limits of the conjecture, Bertalan Bodor, Csaba Szabo and I showed that a vector space over GF(2) of countable dimension with a distinguished non-zero vector has infinitely many reducts. The proof can most easily be seen using an infinite generalisation of the binary Reed–Muller codes.
In the coming semester, CIRCA lunchtime seminars will be on Thursday 1pm in odd weeks in Maths Theatre C (note the change of venue). The first one will be on Thursday, February 1st. Jon Fraser and Shayo Olukoya will be speaking.
There will be a workshop on Groups, Generalisations and Applications at the ICMS in Edinburgh on the afternoon of Wednesday 8 November. Organisers are Jim Howie (Heriot-Watt), Ben Martin (Aberdeen) and Colva Roney-Dougal (St Andrews). Further details are available here.
The next CIRCA lunchtime seminar will be on Thursday 26th October 2917 at 1pm today in Theatre A of Maths. Nayab Khalid and Mun See Chang will be speaking.
Martyn Quick attended the joint meeting of the Edinburgh Mathematical Society and Societat Catalana de Matemàtiques (27-29 September 2017) held at the ICMS in Edinburgh. He was invited to speak at the special session on Geometric Group Theory at this meeting and delivered a talk titled “Presentations for Thompson’s group V and its generalisations”. Colva Roney-Dougal and Colin Campbell also attended.
