Jonathan Lazare Alperin

Alperin at Berkeley in 1981

Jonathan Lazare Alperin (/ˈælpərɪn/; born 1937) is an American mathematician specializing in the area of algebra known as group theory. He is notable for his work in group theory which has been cited over 500 times according to the Mathematical Reviews. The Alperin–Brauer–Gorenstein theorem is named after him.


Alperin attended school at Princeton University and wrote his Ph.D. dissertation in 1961 "On a Special Class of Regular p-Groups" under the direction of Graham Higman. He was awarded a Guggenheim Fellowship in 1974. He has several times (1969, 1979, and 1983) been a visiting scholar at the Institute for Advanced Study.[1] In 2012 he became a fellow of the American Mathematical Society.[2]

Alperin is a professor at the University of Chicago where he has had 22 students and 30 descendants. He has published over 60 papers and his work has been cited over 500 times.

He is also known for his conjecture, (Alperin 1987), a topic of current research in modular representation theory, and for his work on the local control of fusion, (Alperin 1967), part of local group theory. In (Alperin 1970), the Alperin–Brauer–Gorenstein theorem was proven, giving the classification of finite simple groups with quasi-dihedral Sylow 2-subgroups.
