Higher-order beta-matching

Open mrhaandi opened this issue 10 months ago • 0 comments

  • added higher-order matching wrt. beta-equivalence HOMbeta
  • added reduction from SSTS01 to HOMbeta resulting in undecidable HOMbeta

The reduction is quite different from the known technique by Loader [1]. It is based on the technique used for intersection type inhabitation, see IntersectionTypes/Reductions/SSTS01_to_CD_INH.v, sharing a common seed. A write up for a potential publication is in progress.
