Derivatives of Logical Formulas

| Abstract: |
We formalize new decision procedures for WS1S, M2L(Str), and Presburger
Arithmetics. Formulas of these logics denote regular languages. Unlike
traditional decision procedures, we do not translate formulas into automata
(nor into regular expressions), at least not explicitly. Instead we devise
notions of derivatives (inspired by Brzozowski derivatives for regular
expressions) that operate on formulas directly and compute a syntactic
bisimulation using these derivatives. The treatment of Boolean connectives and
quantifiers is uniform for all mentioned logics and is abstracted into a
locale. This locale is then instantiated by different atomic formulas and their
derivatives (which may differ even for the same logic under different encodings
of interpretations as formal words).
The WS1S instance is described in the draft paper A Coalgebraic Decision Procedure for WS1S by the author. |
