Valentina Ivanivna Gorbachuk (born 1937) is a Soviet and Ukrainian mathematician, specializing in operator theory and partial differential equations.
Gorbachuk was born in Mogilev on 25 June 1937; then part of the Soviet Union, it has since become part of Belarus. Her parents worked as an accountant and a telegraphist; in search of better work, they moved to Lutsk in what is now Ukraine when Gorbachuk was a child, and that is where she was schooled. [1]
She applied to study mathematics and mechanics at Taras Shevchenko National University of Kyiv, but was denied because of a "stay in the occupation". Instead, she went to the Lutsk Pedagogical Institute, graduating in 1959. On the advice of one of her faculty mentors there, S.I. Zuhovitsky, [1] she entered graduate study at the NASU Institute of Mathematics, as a student of Yury Berezansky , earning a candidate degree (the Soviet equivalent of a Ph.D.) in the early 1960s. [1] [2]
She continued as a researcher at the Institute of Mathematics for the rest of her career, defending a Doctor of Science (equivalent of a habilitation under the former Soviet system) in 1992. [1]
Gorbachuk is the coauthor, with M. L. Gorbachuk, of two books on operator theory, translated from Russian into English:
In 1998, Gorbachuk won the State Prize of Ukraine in Science and Technology. [1]
Gorbachuk worked closely with her husband, Miroslav L'vovich Gorbachuk (1938–2017), a mathematician with whom she shared her research interests. [1] Their son, Volodymyr Myroslavovich Gorbachuk, is an associate professor of mathematical physics at the Igor Sikorsky Kyiv Polytechnic Institute (National Technical University of Ukraine). [1] [5]
Lev Semenovich Pontryagin was a Soviet mathematician. He was born in Moscow and lost his eyesight completely due to an unsuccessful eye surgery after a primus stove explosion when he was 14. Despite his blindness he was able to become one of the greatest mathematicians of the 20th century, partially with the help of his mother Tatyana Andreevna who read mathematical books and papers to him. He made major discoveries in a number of fields of mathematics, including optimal control, algebraic topology and differential topology.
Mark Grigorievich Krein was a Soviet mathematician, one of the major figures of the Soviet school of functional analysis. He is known for works in operator theory, the problem of moments, classical analysis and representation theory.
Mark Aronovich Naimark was a Soviet mathematician who made important contributions to functional analysis and mathematical physics.
Valentina Mikhailovna Borok was a Soviet Ukrainian mathematician. She is mainly known for her work on partial differential equations.
Anatoly Mykhailovych Samoilenko was a Ukrainian mathematician, an Academician of the National Academy of Sciences of Ukraine, the Director of the Institute of Mathematics of the National Academy of Sciences of Ukraine.

Ivan Georgievich Petrovsky was a Soviet mathematician working mainly in the field of partial differential equations. He greatly contributed to the solution of Hilbert's 19th and 16th problems, and discovered what are now called Petrovsky lacunas. He also worked on the theories of boundary value problems, probability, and on the topology of algebraic curves and surfaces.
David Pinhusovich Milman was a Soviet and later Israeli mathematician specializing in functional analysis. He was one of the major figures of the Soviet school of functional analysis. In the 70s he emigrated to Israel and was on the faculty of Tel Aviv University.
Naum Ilyich Akhiezer was a Soviet and Ukrainian mathematician of Jewish origin, known for his works in approximation theory and the theory of differential and integral operators. He is also known as the author of classical books on various subjects in analysis, and for his work on the history of mathematics. He is the brother of the theoretical physicist Aleksandr Akhiezer.
Vladimir Gilelevich Maz'ya is a Russian-born Swedish mathematician, hailed as "one of the most distinguished analysts of our time" and as "an outstanding mathematician of worldwide reputation", who strongly influenced the development of mathematical analysis and the theory of partial differential equations.
Tatyana Olegovna Shaposhnikova is a Russian-born Swedish mathematician. She is best known for her work in the theory of multipliers in function spaces, partial differential operators and history of mathematics, some of which was partly done jointly with Vladimir Maz'ya. She is also a translator of both scientific and literary texts.
Yuri Ivanovich Petunin was a Soviet and Ukrainian mathematician. Petunin was born in the city of Michurinsk (USSR) on September 30, 1937. After graduating from the Tambov State Pedagogical Institute he began his studies at Voronezh State University under the supervision of S.G Krein. He completed his postgraduate studies in 1962, and in 1968 he received his Doctor of Science Degree, the highest scientific degree awarded in the Soviet Union. In 1970 he joined the faculty of the computational mathematics department at Kyiv State University.
