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…

Blow-up of solutions for discrete semilinear wave equation with the scale-invariant damping
Koji Wada, Kyouhei Wakasa
We consider the blow-up problem for discretized scale-invariant nonlinear dissipative wave equations. It is known that the critical exponents for undiscretized equations (continuou…
