Milenko Petri\'cVisa tehnicka skola, Novi Sad, Yugoslavia
Abstract: Using spectral techniques we prove a theorem giving a necessary and sufficient condition for a generalized direct product (GDP) of strongly connected digraphs (with some additional restrictions) to be a primitive digraph.
Keywords: Primitivity of digraphs, Product of digraphs.
