Person: Dezin, Aleksei Alekseevich
Aleksei Dezin was a Russian mathematician who worked on partial differential equations.
Mathematical Profile (Excerpt):
- Aleksei Alekseevich senior was an important figure in the currency reforms of the 1920s when the chervonet, based on the gold standard, was introduced to replace the rouble which had become worthless.
- Until the end of the war, Dezin served in the army in the Far East region.
- After the war ended and he was released from the army, Dezin returned to Moscow where he completed his secondary education, graduating with the silver medal, after the ten year interruption.
- Of course the Russian doctorate (similar to the German habilitation) is a higher degree and Dezin continued to undertake research with this as his goal.
- However in 1994, when over seventy years of age, Dezin was appointed as a professor in the Department of General Mathematics in the Faculty of Numerical Mathematics and Cybernetics at Moscow State University.
- We have already noted Dezin's 1961 thesis Invariant Differential Operators and Boundary Value Problems.
- Most of the research that Dezin undertook during the rest of his career was presented first in papers and then in a number of monographs, so let us now look at these books.
- Dezin's next little book of 63 pages Equations, operators, spectra (1984) shows him to be a skilful and an innovative expositor.
- In 1990 Dezin published Multidimensional analysis and discrete models in Russian, an English translation being published five years later.
- Dezin had many other talents and interests outside mathematics.
- was a gathering place for a wide circle of their friends, including many distinguished mathematicians and humanitarians and Dezin's students, who were attracted by the intellectual atmosphere.
Born 23 April 1923, Moscow, Russia. Died 4 March 2008, Moscow, Russia.
