Mikhail Borovoi

Mikhail Vol'fovich Borovoi (Russian: Михаи́л Во́льфович Борово́й, Hebrew: מיכאל בורובוי; born February 17, 1951) is a Soviet and Israeli mathematician.

Because of Antisemitism in the Soviet Union of the time, Borovoi could not find a job as a mathematician, and only with the start of Perestroika, in 1987 he got a position of a Senior Researcher at the Khabarovsk Division of the Institute for Applied Mathematics of the Far Eastern Branch of the USSR Academy of Sciences[2] in the Far Eastern city of Khabarovsk.

Jointly with James S. Milne,[5] Borovoi proved[6] Shimura's conjecture in the theory of Shimura varieties, which was the subject of Borovoi's invited talk[7] at the International Congress of Mathematicians, Berkeley, 1986.

He proved that the Brauer-Manin obstruction is the only obstruction to the Hasse principle and weak approximation for homogeneous spaces of connected linear algebraic groups over number fields with connected geometric stabilizers.

[8] Jointly with Cyril Demarche, he proved a similar result for the Brauer-Manin obstruction to strong approximation[9]
