TY: JOUR T1 - Behavioral equivalence of hidden k-logics: an abstract algebraic approach A1 - Babenyshev, Sergey A1 - Martins, Manuel A. N2 - This work advances a research agenda which has as its main aim the application of Abstract Algebraic Logic (AAL) methods and tools to the speci?cation and veri?cation of software systems. It uses a generalization of the notion of an abstract deductive system to handle multi-sorted deductive systems which di?erentiate visible and hidden sorts. Two main results of the paper are obtained by generalizing properties of the Leibniz congruence ? the central notion in AAL. In this paper we discuss a question we posed in [1] about the relationship between the behavioral equivalences of equivalent hidden logics. We also present a necessary and su?cient intrinsic condition for two hidden logics to be equivalent. UR - https://ria.ua.pt/handle/10773/15706 Y1 - 2016 PB - Elsevier
