Eigenfunctions of the Perron-Frobenius operator and the finite-time Lyapunov exponents in uniformly hyperbolic area-preserving maps
Kensuke Yoshida, Hajime Yoshino, Akira Shudo +1
The subleading eigenvalues and associated eigenfunctions of the Perron-Frobenius operator for 2-dimensional area-preserving maps are numerically investigated. We closely examine th…

Scarring in classical chaotic dynamics with noise
Domenico Lippolis, Akira Shudo, Kensuke Yoshida +1
We report the numerical observation of scarring, that is enhancement of probability density around unstable periodic orbits of a chaotic system, in the eigenfunctions of the classi…
