CASL.AlphaConvert
Description
uniquely rename variables in quantified formulas to allow for a formula equality modulo alpha conversion
Synopsis
- alphaEquiv :: Eq f => (f -> f) -> FORMULA f -> FORMULA f -> Bool
- convertFormula :: Int -> (f -> f) -> FORMULA f -> FORMULA f
- alphaConvert :: Int -> (f -> f) -> FORMULA f -> (FORMULA f, Int)

alphaEquiv :: Eq f => (f -> f) -> FORMULA f -> FORMULA f -> Bool Source #
formula equality modulo alpha conversion
convertFormula :: Int -> (f -> f) -> FORMULA f -> FORMULA f Source #
uniquely rename variables in quantified formulas and always quantify only over a single variable
alphaConvert :: Int -> (f -> f) -> FORMULA f -> (FORMULA f, Int) Source #
