We propose a modular approach to defining notions of simulation, and modal logics which characterise them. We use coalgebras to model state-based systems, relators to define notio...
A modified version of the Bellare and Rogaway (1993) adversarial model is encoded using Asynchronous Product Automata (APA). A model checker tool, Simple Homomorphism Verificatio...
From the last decade, modeling of cognitive agents have drawn great attention and provide a new paradigm for addressing fundamental questions in cognitive science. In this paper, a...
The notion of assumption-based framework generalises and re nes the use of abduction to give a formalisation of non-monotonic reasoning. In this framework, a sentence is a non-mon...

Specifications of programs use auxiliary symbols to encapsulate concepts for a variety of reasons: readability, reusability, structuring and, in particular, for writing recursive d...
