Viktor Maslov (mathematician)

Viktor Pavlovich Maslov was born in Moscow on 15 June 1930. He was the son of statistician Pavel Maslov and researcher Izolda Lukomskaya, and the grandson of the economist and agriculturalist Petr Maslov. At the beginning of World War II, he was evacuated to Kazan with his mother, grandmother and other members of his mother's family. In 1953 he graduated from the Physics Department of the Moscow State University and taught at the university. In 1957 he defended his Ph.D. thesis and in 1966, his doctoral dissertation. In 1984, he was elected an academician within Department of Mathematics of the Academy of Sciences of the USSR.{{Cite web|last=|first=|date=|title=Маслов, Виктор Павлович From 1968 to 1998, he headed the Department of Applied Mathematics at the Moscow Institute of Electronics and Mathematics. From 1992 to 2016, he was in charge of the Department of Quantum Statistics and Field Theory of the Physics Faculty of Moscow State University. Maslov headed the laboratory of the mechanics of natural disasters at the Institute for Problems in Mechanics of the Russian Academy of Sciences. He was a research professor at the Department of Applied Mathematics at Moscow Institute of Electronics and Mathematics of Higher School of Economics. ==Scientific activity==

Maslov was known as a prominent specialist in the field of mathematical physics, differential equations, functional analysis, mechanics and quantum physics. He developed asymptotic methods that are widely applied to equations arising in quantum mechanics, field theory, statistical physics and abstract mathematics, that bear his name. Maslov's asymptotic methods are closely related to such problems as the theory of a self-consistent field in quantum and classical statistics, superfluidity and superconductivity, quantization of solitons, quantum field theory in strong external fields and in curved space-time, the method of expansion in the inverse number of particle types. In 1983, he attended the International Congress of Mathematicians in Warsaw, where he presented a plenary report "Non-standard characteristics of asymptotic problems". ==Personal life==

In the early 1970s, he met Lê Vũ Anh, the daughter of Lê Duẩn, then General Secretary of the Communist Party of Vietnam, when she was a student at the Faculty of Physics in Moscow State University. The romance was considered scandalous because Vietnamese students studying abroad were not allowed to have romantic relationships with foreigners and anyone caught would have to be disciplined and may be sent back to Vietnam. In order to avoid trouble, she returned home to marry a Vietnamese student from the same university and wanted to stay in Vietnam to forget her love affair with Maslov. However, she was forced by her father to return to USSR to complete her studies. When she and her husband returned to Moscow, Anh realized that she did not love her husband and could not forget her former lover. She decided to live separately from her husband and secretly went back and forth with Maslov. After being pregnant for the second time, after having a miscarriage for the first time, Anh had enough energy to ask her husband for a divorce in order to be able to marry Maslov. In 1975, she and Maslov married. She gave birth to a daughter on 31 October 1977 named Lena. Meeting her father by chance when he went to USSR for a state visit, Anh confessed all her love affairs. Lê Duẩn did not accept it and tried to lure her back to the country. However, Anh gradually reconciled with her family. After giving birth to her second daughter Tania, Anh gave birth to her son, Anton, on 1981. Anh died shortly after giving birth to her son, due to hemorrhage. Immediately after Anh's death, a dispute arose over the custody of his three children, driven largely by the objections of their grandmother, Nguyen Thuy Nga. She strongly disapproved of Maslov's eccentric parenting style—particularly his refusal to enroll the children in formal schools, instead allowing them to roam the suburbs freely and receive an unconventional education from university lecturers he invited at irregular hours. His behavior also drew political ire; notably, he irritated Le Duan by illustrating to his other children and visiting relatives, through mathematical models, why he believed the Soviet Union was destined to collapse. However, the son that Maslov met was no longer Anton Maslov as before, but a Vietnamese citizen with the new name Nguyễn An Hoàn and he was unable to speak Russian. According to Maslov, Lê Duẩn did not intend to return the child, but also hoped to bring back his daughters. Fearing the loss of his children, Maslov contacted the son of the President of the Supreme Soviet of the Soviet Union Andrei Gromyko, a close friend of Soviet leader Mikhail Gorbachev. He was advised to write to Gorbachev and was promised to convince Gorbachev to read it. After a massive legal struggle, Lê Duẩn gave up the idea of taking him and his children back. However, Nguyen Thuy Nga only relented after Maslov agreed to allow his children to attend school and have a more conventional childhood. ==Selected books==
