Bjarni Jónsson (mathematician)
Bjarni Jónsson (born February 15, 1920 in Draghals , Iceland ; † September 30, 2016 ) was an Icelandic - American mathematician who studied logic, universal algebra and the theory of associations .
He studied at the University of California, Berkeley , where he received his bachelor's degree in 1943 and his doctorate in 1946 with Alfred Tarski (Direct decomposition of finite algebraic systems). Then he was from 1946 instructor and assistant professor at Brown University . In 1956 he became an associate professor and later professor at the University of Minnesota at Minneapolis . Since 1966 he has been a Distinguished Professor at Vanderbilt University . Since 1993 he has been Professor Emeritus there.
Various mathematical concepts are named after him, such as Jonsson-Tarski duality, Jonsson algebras and a type of large cardinal numbers (Jonsson cardinal numbers).
In 1991 he gave the Tarski Lectures . In 1974 he was invited speaker at the ICM in Vancouver ( Varieties of algebras and their congruence varieties ). In 2012 Bjarni Jónsson became a Fellow of the American Mathematical Society .
Peter Fillmore is one of his PhD students .
He is a US citizen. In 1986 he received an honorary doctorate in Reykjavík, where he was also a visiting professor in 1954/55.
