Sabir Gusein-Zade

Sabir Medgidovich Gusein-Zade (Russian: Сабир Меджидович Гусейн-Заде; born 29 July 1950 in Moscow^[1]) is a Russian mathematician and a specialist in singularity theory and its applications.^[2]

He studied at Moscow State University, where he earned his Ph.D. in 1975 under the joint supervision of Sergei Novikov and Vladimir Arnold.^[3] Before entering the university, he had earned a gold medal at the International Mathematical Olympiad.^[2]

Gusein-Zade co-authored with V. I. Arnold and A. N. Varchenko the textbook Singularities of Differentiable Maps (published in English by Birkhäuser).^[2]

A professor in both the Moscow State University and the Independent University of Moscow, Gusein-Zade also serves as co-editor-in-chief for the Moscow Mathematical Journal.^[4] He shares credit with Norbert A'Campo for results on the singularities of plane curves.^[5]^[6]^[7]
