After defining what is a recurrent cycle, ASHBY states that: “If the cycle is wholly contained in a given region, and the lines of behavior lead into the cycle, the cycle is stable”.
ASHBY gives an enlightening example: “Such a cycle is commonly shown by thermostats which, after correcting any gross displacement, settle down to a steady oscillation. In such case the field will show, not convergence to a point but convergence to a cycle” (1960, p.49).
