Isabelle A generic {theorem prover} with support for several {object-logics}, developed by Lawrence C. Paulson in collaboration with {Tobias Nipkow (http://in.tum.de/~nipkow/)} at the {Technical University of Munich}. A system of {type classes} allows polymorphic object-logics with overloading and automatic type inference. Isabelle supports first-order logic - constructive and classical versions; {higher-order logic}, similar to Gordon's HOL; Zermelo Frnkel set theory; an extensional version of {Martin Lf}'s {type theory}, the classical first-order {sequent calculus}, LK; the {modal logics} T, {S4}, and {S43}; and Logic for Computable Functions. An object logic's syntax and inference rules are specified {declaratively} allowing single-step proof construction. {Proof procedures} can be expressed using "tactics" and "tacticals". Isabelle provides control structures for express
