Summary:
In this study, we investigate the oscillation phenomena in a random-coupled network of hard-type oscillators whose nonlinear characteristics are represented by fifth-power polynomials. Recently, we have shown that the chaotic phenomena are seen in the network with soft-type oscillators whose nonlinear characteristics are represented by third-power polynomials. In this paper, for the networks with hard-type oscillators, we show that not only chaotic phenomena but also torus and spatio-temporal patterns such as amplitude switching are observed by changing the coupling coefficients.
