Course objectives
This course delivers focuses on the correspondence between proof theory and typed lambda-calculus and its generalization to the correspondence between computations as proof simplifications and program specifications as types in various formal settings. The contents of the course is relevant for work in many areas of theoretical computer science.
Syllabus
  • Meaning and denotation in logic, tarski and Heyting.
  • natural deduction: calculus, rules, computational interpretation.
  • Curry-Howard isomorphism: lambda-calculus, operational and denotational interpretation, conversion, isomorphism.
  • Normalization theorem: Church-Rosser property, weak normalization, strong normalization.
  • Sequent calculus: structural rules, intuitionistic version, identities, logical rules, properties of the cut-free system, translation between sequent calculus and natural deduction.
  • Strong normalization theorem: reducibility and its properties.
  • Gödels system T, calculus, normalization, expressive power.
  • Coherent spaces, stabil functions, paralel disjunction, product and function spaces, denotational semantics of System T.
  • Sums in natural deduction: problems, standard conversion, commuting conversions, functional calculus.
  • System F: calculus, simple types, free structures, inductive types, Curry-Howard isomorphism, strong normalization.
  • Coherent semantics of the sum; cut-elimination theorem; representation.
