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]
