Phase and frequency linear response theory for hyperbolic chaotic oscillators
Ralf Tönjes, Hiroshi Kori
We formulate a linear phase and frequency response theory for hyperbolic flows, which generalizes phase response theory for autonomous limit cycle oscillators to hyperbolic chaotic…

Exponential system-size dependence of the lifetime of transient spiral chaos in excitable and oscillatory media
Kaori Sugimura, Hiroshi Kori
Excitable media can develop spiral chaos, in which the number of spirals changes chaotically with time. Depending on parameter values in dynamical equations, spiral chaos may perma…
