A survey is given of results about coherence for categories with finite products and coproducts. For these results, which were published previously by the authors in several places...
Essential elements of aspect-oriented programming can be formulated as forms of logic programming. Extensions of Horn Clause rovide richer abstraction and control mechanisms. Defi...
In earlier work [9], we defined CTL model-checking over finite-valued logics with De Morgan negation. In this paper, we extend this work to logics with intuitionistic, Galois an...
Abstract. We present two modal typing systems with the approximation modality, which has been proposed by the author to capture selfreferences involved in computer programs and the...
We solve the open problem of the decidability of Boolean BI logic (BBI), which can be considered as the core of separation and spatial logics. For this, we define a complete phas...
