Tom Leinster

from Wikipedia, the free encyclopedia

Thomas Stephen Hampden "Tom" Leinster (* 1971 ) is a British mathematician and professor at the University of Edinburgh who specializes in category theory.

Leinster received his doctorate in 2000 from the University of Cambridge under Martin Hyland ( Operads in Higher-Dimensional Category Theory ). He then taught in Glasgow and is a professor at Edinburgh University.

He published textbooks on category theory and higher categories and operads . In the 2010s, he was mainly concerned with a generalization of the Euler characteristic in category theory, the magnitude . He also looked at them in metric spaces with application in biology (measurement of biodiversity).

According to him, Leinster groups named (finite groups whose order is equal to the sum of the orders of their normal subgroups).

For Rethinking Set Theory he received the Chauvenet Prize for 2019 .

He is a frequent author and moderator of the academic group blog n-Theory-Café, which covers topics from mathematics, science and philosophy, often from a category theory perspective .

An article by Leinster in the New Scientist received media attention , in which he called for mathematicians not to work for intelligence services for ethical reasons. In German-speaking countries, among others, Der Spiegel and Zeit Online reported on this.
