The Atlas of Irish Mathematics: Mayo (Apr 2018)
This month we complete the first year of our bimonthly surveys of the careers of some mathematically trained people associated with various counties of Ireland. Following Donegal, Wexford, Armagh, Limerick, and Westmeath, this month we focus on Mayo people.
As usual, those listed generally started with a degree in mathematics, maths physics, statistics or a related field, and some careers drifted far from what was studied in university.
The information below is extracted from the Annals of Irish Mathematics & Mathematicians, which currently documents over 3660 people. Corrections, as always, are welcome. Thanks to Paul Greaney (NUIG) and Olivia Bree (SPD) for genealogical research assistance. Last updated 11 Nov 2021.
