Anticipated and Lag Synchronization
In these cases the synchronized state is characterized by a time interval τ such that the dynamical variables of the oscillators, (x1,x2,,...,xn) and (x'1, x'2,...,x'n), are related by x'i(t)=xi(t+τ); this means that the dynamics of one of the oscillators follows, or anticipates, the dynamics of the other. Anticipated synchronization may occur between chaotic oscillators whose dynamics is described by delay differential equations, coupled in a drive-response configuration. In this case, the response anticipates the dynamics of the drive. Lag synchronization may occur when the strength of the coupling between phase-synchronized oscillators is increased.

Famous quotes containing the words anticipated and/or lag:
“Neither party expected for the war, the magnitude, or the duration, which it has already attained. Neither anticipated that the cause of the conflict might cease with, or even before, the conflict itself should cease.”
—Abraham Lincoln (1809–1865)
“I could be well content
To entertain the lag end of my life
With quiet hours.”
—William Shakespeare (1564–1616)
