Properties of palindromes in finite words

Abstract

We present a method which displays all palindromes of a given length from De Bruijn words of a certain order, and also a recursive one which constructs all palindromes of length n+1n+1 from the set of palindromes of length nn. We show that the palindrome complexity function, which counts the number of palindromes of each length contained in a given word, has a different shape compared with the usual (subword) complexity function. We give upper bounds for the average number of palindromes contained in all words of length nn, and obtain exact formulae for the number of palindromes of length 1 and 2 contained in all words of length nn.
