Subject: Announcing Isabelle99-1
To: isabelle-users@cl.cam.ac.uk
Isabelle99-1 is now available. This release continues the line of
Isabelle99, introducing numerous improvements, both internal and user
visible.
In particular, great care has been taken to improve robustness and
ease use and installation of the complete Isabelle working
environment. This includes Proof General user interface support, WWW
presentation of theories and the Isabelle document preparation system.
The most prominent highlights of Isabelle99-1 are as follows.
* Isabelle/Isar improvements (Markus Wenzel)
o Support of tactic-emulation scripts for easy porting of legacy ML
scripts (see also the HOL/Lambda example).
o Better support for scalable verification tasks (manage large
contexts in induction, generalized existence reasoning etc.)
o Hindley-Milner polymorphism for proof texts.
o More robust document preparation, better LaTeX output due to
fake math-mode.
o Extended "Isabelle/Isar Reference Manual".
* HOL/Algebra (Clemens Ballarin)
Rings and univariate polynomials.
* HOL/BCV (Tobias Nipkow)
Generic model of bytecode verification, i.e. data-flow
analysis for assembly languages with subtypes.
* HOL/IMPP (David von Oheimb)
Extension of IMP with local variables and mutually recursive
procedures.
* HOL/Isar_examples (Markus Wenzel)
More examples, including a formulation of Hoare Logic in Isabelle/Isar.
* HOL/Lambda (Stefan Berghofer and Tobias Nipkow)
More on termination of simply-typed lambda-terms; converted into
an Isabelle/Isar tactic emulation script.
* HOL/Lattice (Markus Wenzel)
Lattices and orders in Isabelle/Isar.
* HOL/MicroJava (Gerwin Klein, Tobias Nipkow, David von Oheimb, and
Cornelia Pusch)
Formalization of a fragment of Java, together with a corresponding
virtual machine and a specification of its bytecode verifier and a
lightweight bytecode verifier, including proofs of type-safety.
* HOL/NumberTheory (Thomas Rasmussen)
Fundamental Theorem of Arithmetic, Chinese Remainder Theorem,
Fermat/Euler Theorem, Wilson's Theorem.
* HOL/Real (Jacques Fleuriot)
More on nonstandard real analysis.
* HOL/Prolog (David von Oheimb)
A (bare-bones) implementation of Lambda-Prolog.
