In given work are considered model-theoretical properties of companions of (n1, n2)-Jonsson theory.Also were considered a communications between center and (n1, n2)-Jonsson theory.Herewith considered theories is perfect in the sense of the existence of appropriate model companion.In given article introduced new concepts: (n1, n2)-Jonsson theory, D -α-model companion.New results are shown with respect to model companions of α-Jonsson theory and 1-perfect 1-Jonsson theory.
