Title of the talk: Interaction properties of relational periods
(paper by Vesa Halava and Tero Harju and Tomi Kärkiy)
Abstract: We consider relational periods where the relation is a compatibility relation on words induced by a relation on letters. We introduce three types of periods, namely global, external and local relational periods, and we compare their properties by proving variants of the theorem of Fine and Wilf for these periods.
