文摘
- •
A forced, stochastic van der Pol type birhythmic oscillator is considered.
- •
The noise is correlated.
- •
The analytical treatment allows the reduction to a bistable pseudopotential.
- •
Numerical simulations confirm the effectiveness of the stochastic averaging.
- •
The interplay of the drive and noise produces structural changes.
