Abstract

Combinatorics on words and symbolic dynamics are one of the new branches of mathematics and computer science. In this paper we investigate a class of words with low complexity function its related to digital problem. For a one-digit prime number, consider the sequence of first digit in the decimal representation of powers of that prime number. We have shown that the complexity function of this sequence is a polynomial with degree one, and we find an explicit formula for it.
