Which mathematician contributed most to the decidability of various algebraic groups, Anatoly Maltsev or Semyon Aranovich Gershgorin?
Semyon Aranovich Gershgorin Semyon Aronovich Gershgorin (August 24, 1901 – May 30, 1933) was a Soviet (born in Pruzhany, Belarus, Russian Empire) mathematician. He began as a student at the Petrograd Technological Institute in 1923, became a Professor in 1930, and was given an appointment at the Leningrad Mechanical Engineering Institute in the same year. His contributions include the Gershgorin circle theorem.
Yuri Golfand Yuri Abramovich Golfand (Russian: Ю́рий Абра́мович Го́льфанд ; January 10, 1922, in Kharkiv – February 17, 1994, in Jerusalem) was a Russian and Israeli physicist known, in particular, for his 1971 paper (joint with his student Evgeny Likhtman) where they proposed supersymmetry between bosonic and ferminoic particles by extending the Poincaré algebra with anticommuting spinor generators. The algebra they constructed is also called a Super-Poincaré algebra. In the very same paper they presented the ﬁrst four-dimensional supersymmetric
