Cluster Analysis for Globally Coupled Map using Optimal Transport Distance and Complexity of Attractor-ruin
Koji Wada, Takao Namiki
In this paper, we show the results of the strength of attractorruins for a globally coupled map. The globally coupled map (GCM) is a discrete dynamical system, and here we consider…

Threshold-crossing estimates for time-weighted discrete semilinear wave equations
Koji Wada, Kyouhei Wakasa
In this paper, we consider the initial value problem for a discrete semilinear wave equation with a time weight, obtained by the standard centered finite-difference scheme. The sol…
