Life

Mergeljan was the son of the Armenian Mergelow family. He studied mathematics at the University of Yerevan with a degree in 1947. He worked at this university from 1945 to 1957. At the age of 20, he presented his candidate dissertation , supervised by MW Keldysch and AL Shahinjan , to the Steklow Institute for Mathematics in 1949 he was immediately promoted to a doctorate in physical and mathematical sciences . This made him the youngest doctor of science in the history of the Soviet Union . In 1953 he became a Corresponding Member of the Academy of Sciences of the USSR (AN-SSSR) (which in 1991 became the Russian Academy of Sciences (RAN)), making him the youngest academician in the Soviet Union. In 1951 he set up an approximation theorem known today as Mergeljan's theorem in function theory. A few years later he solved the Sergei Natanowitsch Bernstein approximation problem. In 1954 he went to Moscow , where he changed his previous family name Mergelow to the Armenian form Mergeljan. He worked at the Lomonosov University in Moscow until 1958.

1956 founded Andronik Iossifjan with Mergeljan in Yerevan , the Institute of Mathematical Machines with Computer Center of the Armenian Academy of Sciences (AN-ArmSSR) , its first director was Mergeljan and that is (to 1960) now as Mergeljan Institute known. In the same year Mergeljan became a full member of the AN-ArmSSR, which in 1993 became the Armenian National Academy of Sciences .

1964 to 1968 Mergeljan worked again at the Lomonosov University in Moscow. He then founded and headed the Complex Analysis Department at the Steklow Institute for Mathematics. At the same time he was the deputy academy secretary of the mathematics department of the AN-SSSR. 1971 to 1974 Mergeljan was vice president of the AN-ArmSSR.

Mergeljan was a deputy in the Supreme Soviet of the Armenian SSR during the 5th and 8th sessions. In 1955 he signed the letter of the Three Hundred Critical Scientists of the Soviet Union to the Politburo of the Communist Party of the Soviet Union against Lyskoism . Indira Gandhi had been friends with Mergeljan since the 1950s and visited him in 1978 after her state visit to Moscow.

1982-1986 was Mergeljan rector of Pedinstituts Kirowakan from which the State University of Artsakh to the Republic of Nagorno Karabakh emerged.

In 1990 Mergeljan went to Cornell University as a lecturer . In 1993 he returned to Moscow. In 1996 he finally emigrated to the USA and lived in Los Angeles with his son's family. There, on his 80th birthday, he was awarded the Order of Saint Mesrop Mashtots by the Armenian Consul General on behalf of the Armenian President. At his request, his ashes were buried in Moscow's Novodevichy Cemetery next to his mother and wife.

Mergeljan's scientific work made significant contributions to the theory of the functions of complex variables , to approximation theory including the theory of point-wise approximation by polynomials, and to the theory of potential functions and harmonic functions .
