Sergey Kryzhevich

Sergey Kryzhevich is an Associate Professor at the Institute of Applied Mathematics within the Faculty of Applied Physics and Mathematics at Gdańsk University of Technology. His office is located in Building B, room 518, and he can be contacted at sergey.kryzhevich@pg.edu.pl.

Dr. Kryzhevich's research spans several key areas of mathematical physics and dynamical systems. His primary interests include:

• Dynamical systems and chaos theory
• Billiards with moving boundaries and elastic impacts
• Global controllability of vector fields
• Dynamic-algebraic equations on time scales
• Partial hyperbolicity and shadowing properties
• Magnetohydrodynamic flows

His scholarly output demonstrates a consistent research trajectory from 2013 through 2024, with recent publications focusing on time-varying dynamic-algebraic equations, billiards in rotating systems, and controllability theory. His work often involves international collaborations, particularly with researchers like A. Plakhov and E. Stepanov, indicating active engagement with the global mathematical community.

The thematic evolution of his research shows progression from foundational work in dynamical systems and partial hyperbolicity toward more specialized applications in billiard dynamics with moving boundaries and time scale systems. His interdisciplinary reach extends to bioinformatics, as evidenced by his 2022 work applying manifold learning techniques to SARS-CoV-2 evolution.

Dr. Kryzhevich maintains an active teaching role at Gdańsk University of Technology with 17 courses listed in his teaching portfolio, though specific course details aren't provided in the available information. His research continues to explore fundamental questions in mathematical physics with applications across multiple scientific domains.
