On the maximal run-length function in the Lüroth expansion

Yu Sun, Jian Xu

Received September 9, 2016.   First published January 18, 2018.

Abstract:  We obtain a metrical property on the asymptotic behaviour of the maximal run-length function in the Lüroth expansion. We also determine the Hausdorff dimension of a class of exceptional sets of points whose maximal run-length function has sub-linear growth rate.
Keywords:  Lüroth expansion; run-length function; Hausdorff dimension
