Alexander Andreevich Samarski ( Russian Александр Андреевич Самарский , English transcription Aleksandr Andreevich Samarskii; born February 19, 1919 in Novo-Ivanovskoye , Yekaterinoslav Governorate ; † February 11, 2008 ) was a mathematical mathematician with mathematics and mathematics, with Russian modeling and mathematics concerned.

Life

Samarski studied at Lomonossow University from 1936 , interrupted from 1941 to 1944 in voluntary military service in World War II - among other things, he was wounded in the Battle of Moscow. In 1948 he received his doctorate (candidate thesis). At the same time, he worked with Andrei Nikolajewitsch Tichonow on the mathematical modeling of nuclear weapon explosions and electromagnetic fields in waveguides. Samarski has been studying finite difference methods since then and was the founder of a Soviet school in this field. In 1957 he received his habilitation at the MV Keldysch Institute for Applied Mathematics (Russian doctorate) with a thesis on the solution of nonlinear problems in mathematical physics using the finite difference method. In 1966 he became a corresponding and in 1976 a full member of the Soviet Academy of Sciences . From 1953 he was head of department at the Institute for Applied Mathematics of the Soviet Academy of Sciences and professor at Lomonossow University, where he also received an honorary professorship. He founded the Computational Modeling Department in the Faculty of Numerical Mathematics at Lomonosov University and the Mathematical Modeling Department at the Moscow Physical-Technical Institute. From 1991 to 1998 he headed the Institute for Mathematical Modeling of the Russian Academy of Sciences, which he founded, and was chairman of the Russian National Committee for Mathematical Modeling (Russian part of the International Association for Mathematics and Computers in Simulation (IMACS)).

He was a hero of socialist work , received the Lenin Prize , the State Prize and the Lomonosov Prize of Lomonosov University. He had been a foreign member of the Academy of Sciences of the GDR since 1985 .

plant

Samarski achieved fundamental results in the field of finite difference methods , for example in the stability theory of finite difference methods, the application of lattice approximations to equations in mathematical physics (including non-classical problems and non-linear equations such as in chaotic diffusion) and methods for solving them of grid equations. Samarski and his students developed analytical and numerical methods to solve problems in, for example, nuclear physics , plasma physics , nuclear fusion , magnetohydrodynamics , gas dynamics and hydrodynamics with radiation interaction, laser thermochemistry, convection , ecology and autocatalytic chemical reactions. Samarsky had over 100 doctoral students and his students included five corresponding members of the Russian Academy of Sciences.
