Tiling Periodicity

We contribute to combinatorics and algorithmics of words by introducing new types of periodicities in words.A tiling period of a word w is partial word u such that w can be decomposed into several disjoint parallel copies of u, e.g.a lozenge b Counter Height Table Set is a tiling period of a a b b.We investigate properties of tiling periodicities a
