North British Semigroups and Applications Network


NBSAN is a network of researchers in Scotland and Northern England with interests in semigroup theory and its applications. It is funded chiefly by a grant from the London Mathematical Society, with additional contributions from host departments and occasionally from other sources. It holds two meetings per year in different locations around the region, plus occasional online activities. The main participant universities are East Anglia, Manchester, St Andrews and York, but our activities are open to all interested researchers. Attendance at all meetings is free. We especially welcome graduate students.

For enquiries about individual meetings, please contact the relevant local organiser as described below. To enquire about the network please contact the central coordinator Nóra Szakács. To join the mailing list please contact Mark Kambites.

Next Meeting

The next NBSAN meeting will be held in Manchester on Thursday 20th and Friday 21st June 2024, as a satellite to the 75th British Mathematical Colloquium held between 17th and 20th June. The BMC itself will feature lots of semigroups content, and we expect the conjunction of the two events to attract a significant international semigroups audience for the week. The semigroup programme is organised by Marianne Johnson, Mark Kambites, Dmitry Kudryavtsev, Alex Levine and Nóra Szakács.

The BMC runs from 13:00 on Monday to lunchtime on Thursday, with a casual conference dinner (included in the registration fee) on Wednesday evening (note that this is a different day to previously advertised). NBSAN runs from lunchtime on Thursday until 16:30 on Friday, with a dinner (paid separately) on Thursday evening. On Saturday, for those able to stay, there will be an unofficial social excursion (paid separately, provisionally to Quarry Bank Mill, an industrial heritage site with a working 18th century cotton mill and picturesque gardens).

Semigroups in the BMC Programme. The semigroups content of the BMC will be spread over the duration of the meeting, and will feature:
