Yury Sokolov
Edit ProfileEducation
He studied at Kiev Institute of Peoples Education and graduated in 1921. He completed his Doctor of Philosophy from Kiev University. After completing his Doctor of Philosophy, Sokolov taught at the Institute of Mathematics at the National Academy of Sciences of Ukraine.
Career
He taught at the Applied Mathematics Division of the Academy. His doctorate advisor was Dmitry Grave. His doctorate thesis was in the area of mechanics of particles.
He also taught at many other institutions in Kiev.
Sokolov died on February 2, 1971 in Kiev, Ukraine, Union of the Soviet Socialist Republics.
Sokolov did research on the n-body problem for nearly 50 years. He summarized his work in the 1951 book Singular trajectories of a system of free material points (Russian).
He did research on functional equations and on such practical problems as the filtration of groundwater. He also did research on celestial mechanics and hydromechanics.
Sokolov is also known for "the averaging method with functional corrections" or "the Sokolov method".
This method is for finding approximate solutions to differential and integral equations. Sokolov wrote the book The method of averaging of functional corrections (1967), in which he summaries his many important work. He wrote the book at an elementary level
First part of the book discusses applications of his method to problems which can be modelled by linear integral equations with constant limits.
A number of different sufficient conditions for the approximations to converge and presents error estimates were given. The next three parts of the book first examines the problems which can be modelled by nonlinear integral equations with constant limits and then extend the analysis to the situation where the upper limit is variable.
In the final part of the book, Sokolov"s methods to integral equations of mixed type are examined. He also presented some generalizations of the method in a number of appendices.
