| Research Abstract |
The initial objective was to combine the microcosm principle (a mathematical model of modular construction of computer systems) and Stone-like dualities (a mathematical model of modal logic) and to apply it to system verification. However, in the course of our research with interests in the application of mathematics (category theory in particular) to system verification in a broader sense, we obtained new insights on the formalization of fixed-point logics in a fibration (a mathematical model of logics, used in categorical logic) and its application to model checking. We decided to pursue this new direction, and obtained results on the categorical construction of coinductive predicates. The research is being continued now so that the framework also accommodates inductive predicates.
