报告题目:The recurrence set arising in \alpha-Luroth transformation
报告摘要:\alpha-Luroth transformation is a generalization of the classin b-adic expansion and Luroth expansion. It is given as follows. Let \alpha={A_n}_{n\ge 1} be a countable of intervals which partition (0,1] into half-open intervals numbered right to left. Then the \alpha-Lüroth transformation is defined as the piecewise linear map that maps each subinterval A_n into the whole interval (0,1].
In this talk, we discuss the recurrence properties, more precisely, we study the dimension of the set of points whose forward orbit falls into a shrinking cylinders for infinitely many times.
