The Maths Study Group is an initiative of the
former department of Maths, Stats and Foundation Studies, aimed at providing a
forum for mathematically-minded people, within the Faculty and elsewhere, to meet
and share ideas.
Each week somebody gives an expository talk
with the aim of increasing everybody's mathematical general knowledge.
Talks currently take place at approx. 1630 and are preceded by tea. Location details are emailed nearer the time: let Carrie Rutherford know if you would like to be added to the mailing list.
MSG meetings are currently hybrid in-person/videoconference events. Contact Carrie to get attendance/access details.
