Towards a Calculus of State-based Software Components
LuÃs Soares Barbosa (Dep. Informatica, Universidade do Minho, Portugal)
Abstract: This paper introduces a calculus of state_based software components modelled as concrete coalgebras for some Set endofunctors, with specified initial conditions. The calculus is parametrized by a notion of behaviour, introduced as a strong (usually commutative) monad. The proposed component model and calculus are illustrated through the characterisation of a particular class of components, classified as separable, which includes the ones arising in the so-called model oriented approach to systems design.
