| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | One-dimensional Langevin systems are discussed as a reduced (truncation) model of a stochastic mechanical system with network interactions and the double-well potential. Here we focus on state variables with parameters in the vicinity of the bifurcation point, which behave as early-warning signals. It is shown that the resultant Langevin system can reproduce low order statistics of the state variable in the original network system under a relation among parameters, which corresponds to the fluctuation-dissipation relation without the background double-well potential. | |
