CROSS-LIKE SURFACE WAVES BETWEEN FINITE CYLINDRICAL SHELLS

摘要

We construct a new mathematical model of the interaction of two resonant surface waves in a volume between two cylindrical shells of finite length. For the first time, we establish the existence of chaotic attractors for a system satisfying the resonance conditions for cross-like and forced waves. We also study the regular modes in the system and describe their phase portraits and frequency spectra.
