Abstract
Measuring processes of a single spin-1/2 object and of a pair of spin-1/2 objects in the EPR-Bohm state are modeled by systems of differential equations. The latter model is a local model with hidden variables of the EPR-Bohm gedanken experiment. Although there is no dynamical interaction between the pair of spin-1/2 objects, the model reproduces approximately the quantum-mechanical correlations by coincidence counting. Hence the Bell inequality is violated. This result supports the idea that the coincidence counting is the source of the apparent nonlocality in the EPR-Bohm gedanken experiment.

Roughly speaking, an attractor is an invariant set on which neighboring trajectories accumulate. In our case, a, and a, are just limit cycles. See J.-P. Eckmann and D. Ruelle,Rev. Mod. Phys. 57, 617 (1985).
