FOL: First-Order Logic with Natural Deduction
This directory contains the Standard ML sources of the Isabelle system for
First-Order Logic (constructive and classical versions). For a classical
sequent calculus, see LK. Important files include
- ROOT.ML
- loads all source files. Enter an ML image containing Pure
Isabelle and type: use "ROOT.ML";
- Makefile
- compiles the files under Poly/ML or SML of New Jersey
- ex
- subdirectory containing examples. To execute them, enter an ML image
containing FOL and type: use "ex/ROOT.ML";
