Aleksey Krylov

Alexei Nikolaevich Krylov (Russian Алексей Николаевич Крылов, .. * 3.jul / August 15 1863greg in Wisjaga, government Simbirsk (now Ulyanovsk Oblast ), † October 26, 1945 in Leningrad, Soviet Union) was a Russian naval engineer and mathematician.

He was the son of an artillery officer who attended from 1878 to 1894, the Higher Naval School in Saint Petersburg and was then in the Compass Department of the Hydrographic Office in Ivan Petrovich de Collong, where he worked on the magnetic deviation of compasses. In 1888 he went to the shipbuilding Institute of Marine Academy, where he studied mathematics at Alexander Nikolayevich Korkin. In 1890 he graduated with honors and began to lecture first in representation of Korkin. He then remained there for over 50 years professor. In 1900 he also took over the management of the shipbuilding technical tests on the test tank was consecrated in 1894. In 1908, he was ( in the rank of General ) Chief Inspector Shipbuilding and president of the committee for maritime engineering, the Navy Department, where he did not hesitate even conflicts with official bodies. In 1910 he was therefore his official position again. After the October Revolution of 1917, he sought to build international contacts of Russian science again and traveled as one of the first Russian scientists after the revolution in 1921 to London.

In 1898 he received the Gold Medal of the Royal Institution of Naval Architects for his research on the pitching and rolling of ships. In 1914 he was elected to the Russian Academy of Sciences (1916 as a full member ) and was honorary doctorate from the Moscow State University. 1927 to 1932 he was director of the Institute of Physics and Mathematics of the Academy of Sciences of the USSR. In 1943 he was Hero of the work and received the State Prize.

Krylov made ​​important contributions to hydrodynamics of ships ( he also wrote an article in the Encyclopedia of mathematical sciences ) and built in 1904 a mechanical analog computer for solution of the differential equation problems which may arise (the first in Russia). He also developed mathematical methods further (solution of boundary value problems with Fourier series, convergence of Fourier series, approximate solutions of differential equations, eigenvalue problems, and approximation methods for solving the eigenvalue equation 1931), partly directly on classical works about Johann Albrecht Euler, Carl Friedrich Gauss, Newton, Laplace and Lagrange falling back. According to a 1931 article by him the Krylov spaces were named, form the basis of today Krylov subspace methods.

In 1915 he published the first Russian translation of Isaac Newton's " Philosophiae Naturalis Principia Mathematica ", which through several editions in Russia.

Krylov was married. His daughter Anna married Pyotr Leonidovich Kapitsa physicist and Nobel laureate.

He should not be confused with the Russian mathematicians Nikolai Mitrofanovich Krylov and Vladimir J. Krylov.
