• #### Herbrand’s Theorem as Higher Order Recursion ﻿

[OWP-2018-01] (Mathematisches Forschungsinstitut Oberwolfach, 2018-02-19)
We provide a means to compute Herbrand disjunctions directly from sequent calculus proofs with cuts. Our approach associates to a first-order classical proof $\pi \vdash \exists v F$, where $F$ is quantifier free, an ...
