Sergey Mergelyan was an Armenian scientist, an outstanding mathematician, who is the author of major contributions in Approximation Theory.
Education
He graduated from Yerevan State University in 1947. When he was just 20, in Moscow Steklov Mathematical Institute he was awarded the Union of the Soviet Socialist Republics Doctor of Science degree in mathematics in addition to his Doctor of Philosophy Up today this is an absolute record of getting the highest scientific degree (Doctor of Science) at such young age in former Union of the Soviet Socialist Republics and present Russia.
Career
The modern Complex Approximation Theory is based on Mergelyan"s classical work. He has been a symbol of a young scientist in former Union of the Soviet Socialist Republics. In 1978, after her official visit to Moscow, Gandhi had also a private visit to Yerevan just as a guest of Mergelyan. Mergelyan played a leading role in establishing Yerevan Scientific Research Institute of Mathematical Machines (YerSRIMM) -commonly known as Mergelyan Institute of Mathematical Machinesin 1956.
He became the first director of the institute.
In 1951 he formulated and proved the famous result from complex analysis called Mergelyan"s theorem. This theorem of Mergelyan solved an old classical problem.
Several years later he solved another famous problem, the Sergei Natanovich Bernstein Approximation Problem. Mergelyan also has many important results in other areas of complex analysis including the theory of pointwise approximations by polynomials.
Views
When he was just 24 he became corresponding member of the Academy of Sciences of the Union of the Soviet Socialist Republics (now Russian Academy of Sciences), which, from the point of view of young age, is yet another absolute record among Union of the Soviet Socialist Republics scientists.
Membership
Academy of Sciences of the Union of the Soviet Socialist Republics.
