#### Owicki/Gries in Isabelle/HOL

#### Tobias Nipkow and Leonor Prensa Nieto

We present a formalization of the Gries/Owicki method for correctness
proofs of concurrent imperative programs with shared variables in the
theorem prover Isabelle/HOL. Syntax, semantics and proof rules are
defined in higher-order logic. The correctness of the proof rules
w.r.t. the semantics is proved. The verification of some typical
example programs like producer/consumer is presented.
