Were Pavel Urysohn and Leonid Levin known for the same type of work?
Pavel Urysohn Pavel Samuilovich Urysohn (Па́вел Самуи́лович Урысо́н ) (February 3, 1898 – August 17, 1924) was a Soviet mathematician of Jewish origin who is best known for his contributions in dimension theory, and for developing Urysohn's Metrization Theorem and Urysohn's Lemma, both of which are fundamental results in topology. His name is also commemorated in the terms Urysohn universal space, Fréchet–Urysohn space, Menger–Urysohn dimension and Urysohn integral equation. He and Pavel Alexandrov formulated the modern definition of compactness in 1923.
Murray Levin Murray Burton Levin (1927–1999) was a political science professor at Boston University from 1955 through his retirement in 1989. A progressive who once had been a member of the Communist Party USA, Levin was an unreconstructed radical throughout his academic career. In addition to teaching a popular core course on political science, Levin specialized in teaching Marxist political theory to both undergraduate and graduate students. Long before the collapse of the Soviet Union, Levin eventually came to the conclusion that Marxist theory was not a science, let alone a viable system of economics, but was a powerful propaganda tool to mobilize the masses against capital. Class consciousness would be obtained ultimately when the masses finally revolted against the oligarchy.
