Digitalizing Wick's theorem. ~ Joseph Tooby-Smith. https://arxiv.org/abs/2505.07939 #ITP #LeanProver

Digitalizing Wick's theorem

Wick's theorem is a cornerstone of perturbative quantum field theory. In this paper we announce and discuss the digitalization of Wick's theorem and its proof into the interactive theorem prover Lean 4 as part of the project PhysLean. We do the same for the static and normal-ordered versions of Wick's theorem.
