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 2-3 meetings per year in different locations around the region (in normal times), plus occasional online activities. The main participant universities are East Anglia, Heriot Watt, 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.

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


Due to the COVID-19 situation, we have been organising various online seminars and lectures for the worldwide semigroup community. See the archive page for recent activities. There will be a series of eNBSAN seminars on Zoom in Summer 2021, on Wednesdays at 1pm British Summer Time:

After that we will take a break for August, with the intention of resuming in September.

For security, the meeting link and password will be circulated only to the NBSAN mailing list (or to people who directly request it for an individual talk, supplying some evidence of academic credentials). In the meantime please contact Mark Kambites with any questions or to be added to the mailing list.

Future Meetings

There are currently no physical meetings scheduled, due to uncertainty surrounding the COVID-19 situation. Meetings will resume as soon as possible, and in the meantime there are eNBSAN activities (see above).

To receive announcements about future meetings, please email Mark Kambites and request to be added to the NBSAN mailing list.
