SFI Seminar: Noise-Induced Phenomena in One-Dimensional Maps

SFI News:

The next SFI Seminar is set for 12:15 p.m., Friday, Sept. 6, in the Collins Conference Room at the Santa Fe Institute, 1399 Hyde Park Road.

Yuzuru Sato of Hokkaido University, Japan will present the seminar: Noise-Induced Phenomena in One-Dimensional Maps.

Abstract: Noise-induced phenomena arise out of interaction between deterministic dynamics and stochastic noise. Stochastic resonance, noise-induced synchronization, and noise-induced chaos are typical examples in statistical and nonlinear physics. The central problem in this research area is in which way the asymptotic behavior of the deterministic system is altered by external noise.

The simplest mathematical model for this problem is one-dimensional map stochastically perturbed by external noise. In this presentation, we discuss typical noise-induced phenomena in one-dimensional maps, including recently discovered noise-induced phenomena, such as multiple noise-induced transition, noise-induced statistical periodicity, and noise-induced riddling. An application to nonlinear time-series analysis of rotating fluid is also exhibited.

Note: We are unable to accommodate members of the public for SFI’s limited lunch service; you’re welcome to bring your own.
