Time-dependent finite-dimensional dynamical system representation of breather solutions

Yoritaka Iwata, Yasuhiro Takei

A concept of finite-dimensional dynamical system representation is introduced. Since the solution trajectory of partial differential equations are usually represented within infinite-dimensional dynamical systems, the proposed finite-dimensional representation provides decomposed snapshots of time evolution. Here we focus on analyzing the breather solutions …

Static analysis for coupled nonlinear Klein-Gordon equations with asymmetric parameter settings

Yasuhiro Takei, Yoritaka Iwata

Klein-Gordon equations describe the dynamics of waves/particles in sub-atomic scales. For a system of nonlinear Klein-Gordon equations, a systematic analysis of the time evolution for their spatially uniform solutions has been performed \cite{21takei}. In the study, the parameters (mass, wave propagation speed, …
