RIGHT_OR_PEXISTS_CONV
PairRules.RIGHT_OR_PEXISTS_CONV : conv
Moves a paired existential quantification of the right disjunct outwards through a disjunction.
When applied to a term of the form t \/ (?p. u), the conversion
RIGHT_OR_PEXISTS_CONV returns the theorem:
|- t \/ (?p. u) = (?p'. t \/ (u[p'/p]))
where p' is a primed variant of the pair p that does not contain any
variables free in the input term.
Failure
Fails if applied to a term not of the form t \/ (?p. u).
