Isabelle Côté

Isabelle Côté is Professor of Tropical Marine Ecology in the Department of Biological Sciences at Simon Fraser University, in Vancouver, Canada. She pioneered the use of meta-analysis to reconstruct ecological changes on coral reefs and measure the effectiveness of marine protected areas at enhancing fish and their habitats. She is actively involved in marine protected area issues in Canada. Sh...

Isabelle-91

Min introduces the type form (of object-formulae) and the infix constant −→ (for objectimplication). The constant [[ ]] maps form to the predefined type prop of meta-logic propositions. The proposition [[P ]] should be read as “the formula P is true”; we usually distinguish object-level formulae (form) from meta-level formulae (prop). In practice the brackets can be dropped; parser and pretty-p...

Isabelle/Circus

The Circus specification language combines elements for complex data and behavior specifications, using an integration of Z and CSP with a refinement calculus. Its semantics is based on Hoare and He’s unifying theories of programming (UTP). Isabelle/Circus is a formalization of the UTP and the Circus language in Isabelle/HOL. It contains proof rules and tactic support that allows for proofs of ...

Asynchronous Proof Processing with Isabelle/Scala and Isabelle/jEdit

After several decades, most proof assistants are still centered around TTY-based interaction in a tight read-eval-print loop. Even well-known Emacs modes for such provers follow this synchronous model based on single commands with immediate response, meaning that the editor waits for the prover after each command. There have been some attempts to re-implement prover interfaces in big IDE framew...
