[isabelle] new in the AFP: Abstract Soundness



Abstract Soundness
by Jasmin Christian Blanchette, Andrei Popescu, and Dmitriy Traytel

A formalized coinductive account of the abstract development of Brotherston, Gorogiannis, and Petersen [APLAS 2012], in a slightly more general form since we work with arbitrary infinite proofs, which may be acyclic. This work is described in detail in an article by the authors, published in 2017 in the Journal of Automated Reasoning. The abstract proof can be instantiated for various formalisms, including first-order logic with inductive predicates.
