In the quest for an elegant formulation of the notion of "polycategory" we develop a more symmetric counterpart to Burroni's notion of "T-category", where ...
Abstract. Completely iterative algebras (cias) are those algebras in which recursive equations have unique solutions. In this paper we study complete iterativity for algebras with ...
Final coalgebras for a functor serve as semantic domains for state based systems of various types. For example, formal languages, streams, nonwell-founded sets and behaviors of CCS...
