Leading Researcher 

United Institute of Informatics Problems

National Academy of Sciences of Belarus


Valery Gaiko was born on March 31, 1960 in Stolbtsy, Minsk region, Belarus.

V.Gaiko graduated from the Kolosovo Secondary School in Stolbtsy-2, with gold medal (1977) and the Faculty of Mechanics and Mathematics, Belarusian State University, with honor (1982); completed the postgraduate course of Institute of Mathematics, National Academy of Sciences of Belarus (1986) and the postdoctoral course of Belarusian State University of Informatics and Radioelectronics (1999). From 1987 to 2008 he had been working at the Department of Mathematics, BSUIR (Assistant Professor, Associate Professor, Postdoctoral Fellow). Since 2009 V.Gaiko is Leading Researcher at the UIIP NAS of Belarus.

 In 1993 Valery Gaiko defended his theses “Limit Cycle Bifurcations of Quadratic Autonomous Systems in the Plane” (supervised by Academician N.P.Erugin), got Ph.D. degree and became Associate Professor.

 Dr. Gaiko is a world-known expert in Qualitative Theory of Differential Equations and Bifurcation Theory of Dynamical Systems. He has developed the global bifurcation theory of planar polynomial dynamical systems and has solved Hilbert’s Sixteenth Problem for quadratic systems and Smale’s Thirteenth Problem for Liénard polynomial systems. At present Valery Gaiko has been working on the qualitative analysis of 2D and 3D biomedical and ecological dynamical systems.

Dr. Gaiko has over 300 publications including 2 monographs and over 100 research papers in such international journals as Nonlinear Analysis, Differential Equations and Dynamical Systems, International Journal of Dynamical Systems and Differential Equations, International Journal of Bifurcation and Chaos, Journal of Mathematical Sciences, Applied Mathematics Letters, Advances in Dynamical Systems and Applications, Cybernetics and Physics, Nonlinear Phenomena in Complex Systems. He gave over 300 talks at mathematical conferences, congresses, and special seminars on Theory of Differential Equations and Dynamical Systems in leading international centers of Austria, Belgium, Brazil, Bulgaria, China, Czech Republic, France, Germany, Great Britain, Hungary, India, Italy, Korea, Latvia, Lithuania, Netherlands, Norway, Poland, Slovakia, Spain, Sweden, USA, and CIS countries.
