Alexander Lubotzky

Alexander Lubotzky (Hebrew אלכסנדר לובוצקי; born June 28, 1956 in Ramat Gan ) is an Israeli mathematician who deals with group theory and combinatorics.

Lubotzky studied at Bar- Ilan University in Ramat Gan, where in 1975 he earned his bachelor's degree ( summa cum laude) in 1979 and Harry Furstenberg doctorate (pro- finite groups and the congruence subgroup problem). After that, he was Instructor and Lecturer from 1979 at Bar- Ilan University. At the same time, he was from 1977 to 1982 in the Israeli army in the research and development department. From 1982 he was a Senior Lecturer at the Hebrew University in Jerusalem, since 1985 as an associate professor and since 1989 as a professor ( Maurice and Clara Weil Professorship). 1994 to 1996 he headed the Faculty of Mathematics at the Hebrew University. He was a visiting scholar at Yale University in 1979, 1983 and 2005/2006 at the Institute for Advanced Study, as a visiting professor at Stanford University, the University of Chicago, Yale and Columbia University.

Lubotzky deals with various aspects of group theory and representation theory of groups, with applications in geometry, computer science, number theory and graph theory.

In 1991 he received the Erdös Prize and in 2002 the Rothschild price. He holds honorary doctorates from the University of Chicago and a member of the American Academy of Arts and Sciences. 1990 to 1995 he was editor of the Israel Journal of Mathematics. In 1994 he was invited speaker at the International Congress of Mathematicians (ICM ) in Zurich ( Subgroup Growth ).

In 1996 he was co-founder of The Third Way party, for the 1996 to 1999 he sat as a deputy in the Knesset. There he sat down, inter alia, for compromise in ( intra - Jewish ) religious questions. In the 1999 election, he took up for the Centre Party, but his list was not enough room for an election to the Knesset.

He has been married since 1980 and has six children. He lives in Efrat, which he founded with.
