Theorem gzsumshift 14126

Description: Shifting the indexes of a group sum indexed by consecutive integers. (Contributed by Jim Kingdon, 26-Mar-2026.)

Ref	Expression
gzsumshift.b	⊢ 𝐵 = (Base‘𝐺)
gzsumshift.g	⊢ (𝜑 → 𝐺 ∈ CMnd)
gzsumshift.m	⊢ (𝜑 → 𝑁 ∈ (ℤ_≥‘𝑀))
gzsumshift.f	⊢ (𝜑 → 𝐹:(𝑀...𝑁)⟶𝐵)
gzsumshift.s	⊢ 𝑆 = (𝑗 ∈ (1...(𝑁 + (1 − 𝑀))) ↦ (𝑗 − (1 − 𝑀)))

**Assertion**
Ref	Expression
gzsumshift	⊢ (𝜑 → (𝐺 Σ_gz 𝐹) = (𝐺 Σ_gz (𝐹 ∘ 𝑆)))

Distinct variable groups: 𝑗,𝑀 𝑗,𝑁 𝜑,𝑗 Allowed substitution hints: 𝐵(𝑗) 𝑆(𝑗) 𝐹(𝑗) 𝐺(𝑗)

Proof of Theorem gzsumshift Dummy variable 𝑘 is distinct from all other variables.
