Abstract
We present a constructive analysis of the logical notions of satisfiability and consistency for first-order intuitionistic formulae. In particular, we use formal topology theory to provide a positive semantics for satisfiability. Then we propose a “co-inductive” logical calculus, which captures the positive content of consistency.
► We study satisfiability of a first-order intuitionistic formula. ► We give a constructive algebraic semantics for satisfiability. ► We extend usual sequent calculus by introducing a primitive for satisfiability. ► We prove a soundness and completeness result for our calculus.
