Read e-book online Lectures on the Curry-Howard Isomorphism (Studies in Logic PDF

By Morten Heine Sørensen,Pawel Urzyczyn

The Curry-Howard isomorphism states an awesome correspondence among platforms of formal good judgment as encountered in evidence conception and computational calculi as present in variety idea. For instance,
minimal propositional common sense corresponds to easily typed lambda-calculus, first-order good judgment corresponds to based forms, second-order common sense corresponds to polymorphic varieties, sequent calculus is said to specific substitution, etc.

The isomorphism has many features, even on the syntactic level:
formulas correspond to forms, proofs correspond to phrases, provability corresponds to inhabitation, evidence normalization corresponds to time period relief, etc.

But there's extra to the isomorphism than this. for example, it truly is an outdated idea---due to Brouwer, Kolmogorov, and Heyting---that a confident facts of an implication is a technique that transforms
proofs of the antecedent into proofs of the succedent; the Curry-Howard isomorphism provides syntactic representations of such strategies. The Curry-Howard isomorphism additionally presents theoretical foundations for plenty of smooth proof-assistant structures (e.g. Coq).

This e-book supply an creation to elements of evidence idea and comparable features of variety concept proper for the Curry-Howard isomorphism. it could actually function an creation to any or either one of typed lambda-calculus and intuitionistic logic.

Key good points
- The Curry-Howard Isomorphism handled as universal subject
- Reader-friendly creation to 2 complementary topics: Lambda-calculus and positive logics
- Thorough research of the relationship among calculi and logics
- complex examine of classical logics and keep an eye on operators
- Account of discussion video games for classical and intuitionistic good judgment
- Theoretical foundations of computer-assisted reasoning

Diese Einführung in die Informatik behandelt die fundamentalen Modelle, Formalismen und sprachlichen Konstruktionen sowie die wichtigsten Anwendungsgebiete und technischen Konzeptionen der Informatik. Die Darstellung zeichnet sich durch saubere, formale Fundierung und begriffliche Klarheit aus. Der erste Teil stellt das gesamte Gebiet der problemnahen Programmierung vor, von Algorithmenbegriffen über Techniken der funktionalen und der prozeduralen Programmierung und Datenstrukturen zur Programmiermethodik.
