A Spatial Logic for Querying Graphs

Lu a Cardelli, Philippa Gardner and Giorgio Ghelli1 Abstra t. We study a spatial logi for reasoning about labelled dire ted graphs, and the appli ation of this logi to provide a query language for analysing and manipulating su h graphs. We give a graph des ription using onstru ts from pro ess algebra. We introdu e a spatial logi in order to reason lo ally about disjoint subgraphs. We extend our...

Realizing Real-Time Systems from Synchronous Language Specifications

ABSTRACT Syn hronous languages spe ify rea tions of the rea tive/realtime systems to its environment within the language. This makes it easier to validate and verify the systems relative to the assumptions and notions of simultaneity. However, on rete embedding of the ode makes it ne essary to predi t time for rea tions of the underlying run-time systems and the sensors so that the stri t notio...

Global Induction Mechanisms in a Μ - Calculus with Explicit Approximations ∗

We investigate a Gentzen-style proof system for the rstorder μal ulus based on y li proofs, produ ed by unfolding xed point formulas and dete ting repeated proof goals. Our system uses expli it ordinal varia...
