Abstract

In DOI:10.1017/etds.2022.2 the author proved that for each integer kk there is an implicit number M>0M > 0 such that if b1,,bkb_1, \cdots , b_k are multiplicatively independent integers greater than MM, there are infinitely many integers whose base b1,b2,,bkb_1, b_2, \cdots , b_k expansions all do not have zero digits. In this paper we don't require the multiplicative independence condition and make the result quantitative, getting an explicit value for MM. We also obtain a result for the case when the missing digit(s) may not be zero. Finally, we extend our method to study various missing-digit sets in an algebraic setting.
