Webcalled Henge decomposition [68], which served to provide a simple proof of the BPHZ theorem [69]. This mapping also allowed to establish a direct correspondence between overlapping divergences in Feynman parameter space and in momentum space [67]. In this context, one should also mention the formulation of renormalisation using Hopf WebA Central Limit Theorem for Non-Commuting Variables We additionally consider the momentum operators p̂i , the non-commuting conjugate variables of the position operators x̂i , and introduce the blocked variable P̂ 1 P̂ = p̂1 ⊗ 1̂2 · · · ⊗ 1̂ N + 1̂1 ⊗ p̂2 · · · ⊗ 1̂ N + · · · + 1̂1 ⊗ 1̂2 · · · ⊗ p̂ N , N 1 N ...
