Popova I. The fundamental categories of Ukrainian syntax in formal-grammatical and metalinguistic aspects

The thesis presents the triad syntactic unit, link, and model. The general system of contemporary Ukrainian syntactic units is given as a hierarchical sequence of basic, principal, derivative, analytical and analytical search constructs. The set of syntactic links is divided into two subsets: closed including systematically qualified syntactic relations, and open indicating non-standard or (not qualified officially) links not qualified officially. The thesis presents the general principles of linguistic modeling with its theoretical apparatus. Qualifying the mapping of words set into class set and image contamination as leading operations is suggested. The structural models of supraphrasal unity and text have been built for the first time.
