LK: Classical First-Order Sequent Calculus
This directory contains the Standard ML sources of the Isabelle system for
First-Order Logic as a classical sequent calculus. (For a Natural Deduction
version, see FOL.) 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 LK and type: use "ex/ROOT.ML";
