Title:Term-Generic Logic
Author(s):Popescu, Andrei; Rosu, Grigore
Subject(s):Computer Science
Abstract:Term-generic logic (TGL) is a first-order logic parameterized with terms defined axiomatically (rather than constructively), by requiring them to only provide generic notions of free variable and substitution satisfying reasonable properties. TGL has a complete Gentzen system generalizing that of first-order logic. A certain fragment of TGL, called Horn^2 possesses a much simpler Gentzen system, similar to traditional typing derivation systems of lambda-calculi. Horn^2 appears to be sufficient for defining a whole plethora of lambda-calculi as theories inside the logic. Within intuitionistic TGL, a Horn^2 specification of a calculus is likely to be adequate by default. A bit of extra effort shows adequacy w.r.t. classic TGL as well, endowing the calculus with a complete loose semantics.
