Were Pavel Alexandrov and Yuri Matiyasevich both working in the same area of mathematics?
Yuri Matiyasevich Yuri Vladimirovich Matiyasevich, (Russian: Ю́рий Влади́мирович Матиясе́вич ; born March 2, 1947, in Leningrad) is a Russian mathematician and computer scientist. He is best known for his negative solution of Hilbert's tenth problem (Matiyasevich's theorem), which was presented in his doctoral thesis at LOMI (the Leningrad Department of the Steklov Institute of Mathematics).
Yoichi Miyaoka Yoichi Miyaoka (宮岡 洋一 , Miyaoka Yōichi ) is a mathematician who works in algebraic geometry and who proved (independently with Yau) the Bogomolov–Miyaoka–Yau inequality in an Inventiones Mathematicae paper ().
