摘要
We show that the recurrence rates of Laurent series about continued fractions almost surely coincide with their pointwise dimensions of the Haar measure. Moreover, let E-alpha,E-beta be the set of points with lower and upper recurrence rates alpha, beta (0 <= alpha <= beta <= infinity), we prove that all the sets E-alpha,E-beta are of full Hausdorff dimension. Then the recurrence sets E-alpha,E-beta have constant multifractal spectra.
