Critical bases for ternary alphabets
Abstract
Glendinning and Sidorov discovered an important feature of the Komornik-Loreti constant q'≈1.78723 in non-integer base expansions on two-letter alphabets: in bases 1<q<q' only countably numbers have unique expansions, while for q q' there is a continuum of such numbers. We investigate the analogous question for ternary alphabets.
