kinetics and combustion, gas-turbine engines, radiophysics, theoretical 
physics, resistance of materials and the theory of elasticity, gas dynamics, 
electrical engineering, theoretical mechanics, mathematics, and electronics. 
The research work of the Institute encompasses many fields, as exemplified 
by the Institute’s Trudy, which is divided into several volumes, for example, 
"Research in Mechanics and Applied Mathematics" and "Research in Physics and 
Radio Engineering". 
Research at the Institute is primarily theoretical, although 
instruments are designed and constructed in the Chair of Electron and Ion 
Apparatus. Students and other institute personnel often receive guidance 
and help from well-known personnel employed at other research facilities 
in Moscow. 
Some of the best work at the Institute is in the fields of 
structural mechanics and mathematics, Yu. P. Krivenkov, for example, has 
specialized in investigations of the equation of Euler=Poisson=-Darboux; 
I. V. Livartovskiy, in the use of Lyapunov criteria for the stability of 
systems of differential equations; and M. A. Neymark, in group theory. 
Also, there is much work on creep, sandwich materials, stresses around 
holes, and plastic flow. Candidates A. L. Rabinovich and V. 0. Geogdzhayev 
have been outstanding in this work. 
Several investigators study fluid flow and aerodynamics. Most 
interesting are the investigations by V. P. Mugalov of the turbulent 
boundary layer in supersonic flow. Other investigators study gas-turbine 
engines, specifically, the combustion processes in the engine and the 
heat-transfer problems associated with its operation. In the field of gas 
dynamics, there have been several studies on shock waves and detonations. 
Radio communication is a major interest at the Institute. In 
addition to work on communication theory, there is much work done on the 
electronic apparatus itself. B. V. Bondarenko and Yu. G. Tolstov have 
examined semiconductors for use as power rectifiers and thermionic cathodes. 
V. I. Murontsev, working under Prof. Manayev, is studying the electronics of 
transistor amplifiers, and V. A. Shcheglov is doing theoretical work on 
masers.
