Research Focus
Dr. Yury A. Stepanyants focuses on the field of applied mathematics, particularly nonlinear wave theory. His extensive research includes the study of internal solitons in the ocean, their interactions, and effects on underwater acoustics. He has also explored the propagation of nonlinear surface and internal gravity waves in rotating oceans, the self-focusing of dark solitons in nonlinear media, and wave behavior in hydrodynamic shear flows. Dr. Stepanyants’ contributions are documented in numerous influential publications, highlighting his expertise in soliton theory, nonlinear wave dynamics, and their practical applications in oceanography and fluid mechanics.
