Center was built to serve the scientific and industrial needs of eastern 
Siberia. It works on methods of computer mathematics, the theory of pro- 
gramming, and the solution of other theoretical problems.

Description: 
This institute is concerned primarily with structural mechanics. 
Much of its research is on plates, shells, and bars, with particular emphasis 
on creep and plasticity and on anisotropic, orthotropic, and sandwich or 
layered plates and shells. Much of the mathematical research leans toward 
pure mathematics, but infinite series, their use, and convergence also have 
been investigated in connection with calculations of structural elements. 
A. G Bagdoyev and E. M. Nersesyan have concentrated their efforts 
on the transmission of pressures and shock waves in compressible and incom- 
pressible liquids.
