Normal Order uncontracted some

FieldSpecification.WickAlgebra.normalOrder_uncontracted_some

Plain-language statement

For a list φs = φ₀…φₙ of 𝓕.FieldOp, a Wick contraction φsΛ of φs, an element φ of 𝓕.FieldOp, a i ≤ φs.length and a k in φsΛ.uncontracted, then 𝓝([φsΛ ↩Λ φ i (some k)]ᵘᶜ) is equal to the normal ordering of [φsΛ]ᵘᶜ with the 𝓕.FieldOp corresponding to k removed. The proof of this result ultimately is a consequence of definitions.

Exact Lean statement

lemma normalOrder_uncontracted_some (φ : 𝓕.FieldOp) (φs : List 𝓕.FieldOp)
    (i : Fin φs.length.succ) (φsΛ : WickContraction φs.length) (k : φsΛ.uncontracted) :
    𝓝(ofFieldOpList [φsΛ ↩Λ φ i (some k)]ᵘᶜ)
    = 𝓝(ofFieldOpList (optionEraseZ [φsΛ]ᵘᶜ φ ((uncontractedFieldOpEquiv φs φsΛ) k)))
