CORSO DI DOTTORATO

Area Tematica

Logica Computazionale

Il Prof. Dale Miller

INRIA Saclay & Laboratoire d’Informatique, LIX

Ecole polytechnique, PALAISEAU Cedex, FRANCE,

terrà un corso dal titolo

Proof Search and Computation.

Scopo e contenuto: illustrare il ruolo della logica nella specifica delle computazioni e della "proof search" come approccio alla programmazione logica. Il corso sarà suddiviso in due parti:

1. Fondamenti, lezioni tenute da Dale Miller

2. Applicazioni, lezioni ed esercitazioni tenute da A. Momigliano e M.Ornaghi

Pre-requisiti: conoscenza di base di logica

Programma della I parte:

• The first three lectures will be taken from the lecture notes [LN2010] and will cover the basics of sequent calculus and its uses in the specification of logic programming languages.

• The fourth lecture will show how logic specifications can be applied to the specification of structured operational semantics (following the material in [BEATCS08]).

• The fifth lecture will focus on the role of fixed points in the specification and reasoning of computation (following [LPAR07]).

Programma della II parte:

• The first three lectures will address the use of lambda.tree syntax and the proof search approach to model checking with Bedwyr [MFS], exemplifying it with the specification of a lazy functional programming language, namely its static and operational semantics and the related notion of contextual equivalence.

• The last two lectures will introduce interactive theorem proving over this syntax with the Abella system [2LEV] and explore some case studies, such as formally verifying type preservation, and leading to congruence of contextual equivalence  [ASOS,OPT].
