Description: 
The Steklov Institute is the most prominent Soviet research institute 
in the fields of pure and applied mathematics. Divisions of the parent 
institute in Moscow include a computation center, equipped with a URAL 1 and 
a BESM-II computer, and the Department of Applied Mathematics, the Department 
of Mathematical Statistics, and the Department of Theoretical Physics. There 
is a branch of the Institute in Leningrad. 
Although the Institute's work in pure mathematics is quite varied, 
there are concentrations of effort in certain applied fields. A group of 
scientists, including L. S. Pontryagin, has concentrated on optimal control 
theory. lordanskiy works on the mathematics of plasma physics, V. A. 
Solonnikov and others study magnetohydrodynamics, and V. A. Shakhbazyan’s 
field is quantum electrodynamics. Other areas of interest are ferromagnetism, 
superconductivity, cybernetics and algebraic logic, general relativity, 
information theory, propagation of radio waves, and propagation of shock waves 
due to an explosion. 
The Institute works closely with other organizations. A group 
including V. A. Yegorov was responsible for calculating the Lunik trajec- 
tories. B. V. Medvedev works closely with members of the Joint Institute of 
Nuclear Research. And in 1961, the Institute cooperated with the Leningrad 
and Gor'kiy National Economic Councils and the Scientific-Research Institute 
for Labor in determining the required numbers of clerical workers in machine- 
manufacturing plants. 
A Trudy is published irregularly throughout the year.
