抄録: | We consider hyperbolic random complex dynamical systems on the Riemann sphere with separating condition and multiple rmnimal sets. We investigate the Hölder regularity of the function T of the probability of tending to one minimal set, the partial derivatives of T with respect to the probability parameters, which can be regarded as complex analogues of the Takagi function, and the higher partial derivatives C of T. Our main result gives a dynamical description of the pointwise Hölder exponents of T and C, which allows us todetermine the spectrum of pointwise Hölder exponents by employing the multifractal formalism in ergodic theory. Also, we prove that the bottom of the spectrum $alpha$_{-} is strictly less than 1, which allows us to show that the averaged system acts chaotically on the Banach space C^{ $alpha$} of $alpha$-Hölder continuous functions for every $alpha$in($alpha$_{-}, 1) , though the averaged system behaves very mildly (e.g. we have spectral gaps) on C^{ $beta$} for small $beta$>0. |
