On the periodic Schrödinger–Boussinesq system
Journal of Mathematical Analysis and Applications, 2010 We study the local and global well-posedness of the periodic boundary value problem for the nonlinear Schrödinger-Boussinesq system. The existence of periodic pulses as well as the stability of such solutions are also considered.

The ways to form midi-fullerens structure exemplified by С22, С24 and С26 isomers
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2023 In this paper, the possible ways of forming the midi-fullerene isomers, namely C22, C24 and C26, have been systematized. Three simplest mechanisms for their synthesizing are known.

ON PERIODIC DYNAMICAL SYSTEMS [PDF]
Chinese Annals of Mathematics, 2004 In this paper, we investigate the existence and the global stability of periodic solution for dynamical systems with periodic interconnections, inputs and self-inhibitions. The model is very general, the conditions are quite weak and the results obtained are universal.

Influence of radial clearance on nonlinear dynamics of a two-span three-support rotor system [PDF]
E3S Web of Conferences, 2021 Aiming at the structural form of a certain rotor system, a double-span three-support rotor system model is established. It is supported by three rolling bearings and has a typical nonlinear characteristic.

Periodic Solutions of a Periodic FitzHugh–Nagumo System [PDF]
International Journal of Bifurcation and Chaos, 2015 Recently some interest has appeared for the periodic FitzHugh–Nagumo differential systems. Here, we provide sufficient conditions for the existence of periodic solutions in such differential systems.

Periodic‐phase‐diagram similarity method for weak signal detection
International Journal of Mechanical System Dynamics, 2021 The periodic‐phase‐diagram similarity method is proposed to identify the frequency of weak harmonic signals. The key technology is to find a set of optimal coefficients for Duffing system, which leads to the periodic motion under the influence of weak ...
