Bootstrapping Inductive and Coinductive Types in HasCASL

Lutz Schröder.

We discuss the treatment of initial datatypes and final process types in the wide-spectrum language HasCASL. In particular, we present specifications that illustrate how datatypes and process types arise as bootstrapped concepts using HasCASL's type class mechanism, and we describe constructions of&nbsp;[&hellip;]

Coalgebraic Satisfiability Checking for Arithmetic $\mu$-Calculi

Daniel Hausmann ; Lutz Schröder.

The coalgebraic $\mu$-calculus provides a generic semantic framework for fixpoint logics over systems whose branching type goes beyond the standard relational setup, e.g. probabilistic, weighted, or game-based. Previous work on the coalgebraic $\mu$-calculus includes an exponential-time upper bound&nbsp;[&hellip;]
