Topological automata
On an equivalence of system-theoretical and categorical concepts
Correctness of horizontal and vertical composition for implementation concepts based on constructors and abstractors.
A new implementation concept for parameterized specifications based on constructors and abstractors was recently introduced by Orejas, Navarro and Sánchez which includes most of the implementation concepts in the literature for initial as well as loose semantics. In this paper we redefine vertical and different kinds of horizontal compositions using the new concept of semi-pushout defined for a mixture of signature and specification morphisms. The main results concerning correctness of horizontal...
