In formal language theory, James Rogers published a series of innovative papers generalising strings and trees to higher dimensions.Motivated by applications in linguistics, his go...
Abstract. We extend the theory of (co-)spans as a means of providing an algebraic approach to complex interactions as they arise in software-intensive systems. In order to make int...
This paper describes the main features of several tools concerned with the analysis of either Maude specifications, or of extensions of such specifications: the ITP, MTT, CRC, Ch...
Abstract. We present a coalgebraic semantics for reasoning about information update in multi-agent systems. The novelty is that we have one structure for both states and actions an...
We motivate and present a logical semantic approach to types for concurrency and to the soundness of related systems. The approach is illustrated by the development of a generic ty...
In this paper we discuss a uniform method for constructing free modal and distributive modal algebras. This method draws on works by (Abramsky 2005) and (Ghilardi 1995). We revisit...
Besides functional correctness, specifications must describe other properties of permissible implementations. We want to use simple algebraic techniques to specify resource usage ...
