On the time-evolution of resonant triads in rotational capillary-gravity water waves
Rossen I. Ivanov, Calin I. Martin
We investigate an effect of the resonant interaction in the case of one-directional propagation of capillary-gravity surface waves arising as the free surface of a rotational water…
Integrable Cosmological Model with van der Waals Gas and Matter Creation
Rossen I. Ivanov, Emil M. Prodanov
A cosmological model with van der Waals gas and dust has been studied in the context of a three-component autonomous non-linear dynamical system involving the time evolution of the…
Van der Waals Universe with Adiabatic Matter Creation
Rossen I. Ivanov, Emil M. Prodanov
A FRWL cosmological model with perfect fluid comprising of van der Waals gas and dust has been studied in the context of dynamical analysis of a three-component autonomous non-line…
Riemann-Hilbert problem, integrability and reductions
Vladimir S. Gerdjikov, Rossen I. Ivanov, Aleksander A. Stefanov
The present paper is dedicated to integrable models with Mikhailov reduction groups Their Lax representation allows us to prove, that their solution is e…
Expressing Trust with Temporal Frequency of User Interaction in Online Communities
Ekaterina Yashkina, Arseny Pinigin, JooYoung Lee +4
Reputation systems concern soft security dynamics in diverse areas. Trust dynamics in a reputation system should be stable and adaptable at the same time to serve the purpose. Many…
