TITLE: cut-elimination provable in PRA
QUESTION [8 upvotes]: What is the standard reference for the provability of the cut-elimination theorem in PRA?
Update: Rasmus Blanck has offered a reference for a system other than Gentzen's $\mathfrak L \mathfrak K$. The bounty is for a reference for the provability of the cut-elimination theorem for the sequent calculus $\mathfrak L \mathfrak K$ in PRA.

REPLY [2 votes]: I think the chapter "Proof Theory: Some Applications of Cut-Elimination", by Helmut Schwichtenberg, from "Handbook of Mathematical  Logic", might be what you are looking for.
