Hiding message in Delay Time: Encryption with Synchronized time-delayed systems
Won-Ho Kye, Muhan Choi, Chil-Min Kim +1
We propose a new communication scheme that uses time-delayed chaotic systems with delay time modulation. In this method, the transmitter encodes a message as an additional modulati…
Warped products and the Reissner-Nordström-AdS black hole
Soon-Tae Hong, Jaedong Choi, Young-Jai Park
We study a multiply warped product manifold associated with the Reissner-Nordstrom-AdS metric to investigate the physical properties inside the black hole event horizons. Our resul…
Origin of the Transition Inside the Desynchronized State in Coupled Chaotic Oscillators
Chil-Min Kim, Won-Ho Kye, Sunghwan Rim +4
We investigate the origin of the transition inside the desynchronization state via phase jumps in coupled chaotic oscillators. We claim that the transition is governed by type-I in…
Map representation of the time-delayed system in the presence of Delay Time Modulation: an Application to the stability analysis
Won-Ho Kye, Muhan Choi, Tae-Yoon Kwon +2
We introduce the map representation of a time-delayed system in the presence of delay time modulation. Based on this representation, we find the method by which to analyze the stab…
Characteristics of a Delayed System with Time-dependent Delay Time
Won-Ho Kye, Muhan Choi, Sunghwan Rim +3
The characteristics of a time-delayed system with time-dependent delay time is investigated. We demonstrate the nonlinearity characteristics of the time-delayed system are signific…
Symplectic Embedding of a Massive Vector-Tensor Theory with Topological Coupling
Yong-Wan Kim, Chang-Yeong Lee, Seung-Kook Kim +1
In the symplectic Lagrangian framework we newly embed an irreducible massive vector-tensor theory into a gauge invariant system, which has become reducible, by extending the config…
