报告摘要:
Let β > 1 and x ∈ [0, 1) be two real numbers. For any y ∈ [0, 1), the maximal
run-length function r_{x}(y, n) (with respect to x) is defined to be the maximal
length of the prefix of x’s β-expansion which appears in the first n digits of y’s.
In this talk, we introduce the metric properties of the maximal run-length function
and apply them to the hitting time, which generalizes many known results. In
the meantime, the fractal dimensions of the related exceptional sets are also
determined.
