Scientific interests concern mathematical problems of control theory, including: stability and oscillations of nonlinear sampled-data systems considered in a continuous time (systems with a pulse modulation); problems of matrix algebra encountered in control theory.
Biography
Graduated from Faculty of Mathematics and Mechanics of Leningrad (now St. Petersburg) State University in 1975 (Department of Theoretical Cybernetics). Ph.D. thesis was defended in 1981. A list of my works contains more than 60 titles, including two monographs.
Soros Associate Professor (1995).
