Abstract
By the projection of words or languages to a set of symbols the omission of all those ones not belonging to the given set is meant. This operation has a fundamental role in the algebraic representation of concurrent behaviour of sequential processes. Namely, permissible sequences of a superposed (merged) system of sequential components fin the sense of [43 and [8] have the characteristic property that when projecting one of them into any of the components the resulting sequence will also be a permissible one for that component.
