Pavel Sergeyevich Alexandrov (Russian: Па́вел Серге́евич Алекса́ндров), sometimes romanized Aleksandroff or Aleksandrov (May 7, 1896–November 16, 1982) was a Soviet Russian mathematician. He wrote about three hundred papers, making important contributions to set theory and topology.
In topology, the Alexandroff compactification and the Alexandrov topology are named after him.
Alexandrov attended Moscow State University where he was a student of Dmitri Egorov and Nikolai Luzin. Together with Pavel Urysohn, he visited the University of Göttingen in 1923 and 1924. After getting his Ph.D. in 1927, he continued to work at Moscow State University and also joined the Steklov Mathematical Institute. He made lifelong friends with Andrey Kolmogorov, about whom he said: "in 1979 this friendship [with Kolmogorov] celebrated its fiftieth anniversary and over the whole of this half century there was not only never any breach in it, there was also never any quarrel, in all this time there was never any misunderstanding between us on any question, no matter how important for our lives and our philosophy; even when our opinions on one of these questions differed, we showed complete understanding and sympathy for the views of each other."[1] The two were involved in a homosexual relationship in the 1930s.
Alexandrov was an active participant in the political offensive against Luzin which is known as the Luzin affair (1936).
He had a number of students, including Aleksandr Kurosh, Lev Pontryagin and Andrey Tychonoff. He was made a member of the Russian Academy of Sciences in 1953.
Some researchers speculated that he was homosexual.[2][3]
Pavel Alexandrov should not be confused with Aleksandr Danilovich Aleksandrov, another mathematician at the Steklov Institute.
