In this paper, we describe a first-order linear time temporal logic (LTL) model checker based on multiway decision graphs (MDG). We developed a first-order temporal language, LMDG ...
In 1974 R. Fagin proved that properties of structures which are in NP are exactly the same as those expressible by existential second order sentences, that is sentences of the form...
Rational graphs are a family of graphs defined using labelled rational transducers. Unlike automatic graphs (defined using synchronized transducers) the first order theory of these...
In her book "The Iconic Logic of Peirce's Graphs", S. J. Shin elaborates the diagrammatic logic of Peirce's Existential Graphs. Particularly, she provides trans...
Simple Conceptual Graphs (SGs) are used to represent entities and relations between these entities: they can be translated into positive, conjunctive, existential first-order log...
