Properties of a stability for positive Jonsson theories
Қарағанды университетінің хабаршысы. Математика сериясы, 2015 Actually, we study the connections of the Δ-PM-theories with their centers in the enrich signature. The properties of various companions of some Δ-PM-theories and their connection with this theory are considered on the language of the central types of ...
