Classical logic is non-constructive in various ways. Intuitionistic logic is intended to capture a more “constructive” kind of reasoning characteristic of a ...

In this course we give an introduction to intuitionistic logic. We concentrate on the propositional calculus mostly, make some minor excursions to the ...

There are basically two ways to view intuitionistic logic: (i) as a philosoph ical–foundational issue in mathematics, (ii) as a technical discipline within.

Intuitionistic logic has developed as a result of certain philosophical views on the foundation of mathematics, known as intuitionism.

Propositional Intuitionistic Calculus. Propositional formulae are built from a countable set of propositional variables Var = {p, q, r, . . .}.

A first order intuitionistic Kripke model is a structure M = hW, R,D,αi. Here R is a preorder relation on a non-empty set W, D is a function that maps each ...

Intuitionist logic is often understood as similar to classical logic except that it denies the principle of excluded middle.

Intuitionistic logic is a weakening of classical logic by omitting, most promi- nently, the principle of excluded middle and the reductio ad absurdum rule.

The problem of building the intuitionistic logic of proofs has two distinct parts. Firstly, one has to answer the question about propositional logical ...
