Abstract
We consider nonequilibrium probabilistic dynamics in logisticlike maps [Formula presented], [Formula presented] at their chaos threshold: We first introduce many initial conditions within one among [Formula presented] intervals partitioning the phase space and focus on the unique value [Formula presented] for which the entropic form [Formula presented] linearly increases with time. We then verify that [Formula presented] vanishes like [Formula presented] [[Formula presented]]. We finally exhibit a new finite-size scaling, [Formula presented]. This establishes quantitatively, for the first time, a long pursued relation between sensitivity to the initial conditions and relaxation, concepts which play central roles in nonextensive statistical mechanics.
