Theorem plymullem1 25735

Description: Derive the coefficient function for the product of two polynomials. (Contributed by Mario Carneiro, 23-Jul-2014.)

**Hypotheses**
Ref	Expression
plyaddlem.1	⊢ (𝜑 → 𝐹 ∈ (Poly‘𝑆))
plyaddlem.2	⊢ (𝜑 → 𝐺 ∈ (Poly‘𝑆))
plyaddlem.m	⊢ (𝜑 → 𝑀 ∈ ℕ₀)
plyaddlem.n	⊢ (𝜑 → 𝑁 ∈ ℕ₀)
plyaddlem.a	⊢ (𝜑 → 𝐴:ℕ₀⟶ℂ)
plyaddlem.b	⊢ (𝜑 → 𝐵:ℕ₀⟶ℂ)
plyaddlem.a2	⊢ (𝜑 → (𝐴 “ (ℤ_≥‘(𝑀 + 1))) = {0})
plyaddlem.b2	⊢ (𝜑 → (𝐵 “ (ℤ_≥‘(𝑁 + 1))) = {0})
plyaddlem.f	⊢ (𝜑 → 𝐹 = (𝑧 ∈ ℂ ↦ Σ𝑘 ∈ (0...𝑀)((𝐴‘𝑘) · (𝑧↑𝑘))))
plyaddlem.g	⊢ (𝜑 → 𝐺 = (𝑧 ∈ ℂ ↦ Σ𝑘 ∈ (0...𝑁)((𝐵‘𝑘) · (𝑧↑𝑘))))

**Assertion**
Ref	Expression
plymullem1	⊢ (𝜑 → (𝐹 ∘_f · 𝐺) = (𝑧 ∈ ℂ ↦ Σ𝑛 ∈ (0...(𝑀 + 𝑁))(Σ𝑘 ∈ (0...𝑛)((𝐴‘𝑘) · (𝐵‘(𝑛 − 𝑘))) · (𝑧↑𝑛))))

Distinct variable groups: 𝐴,𝑛 𝑘,𝑛,𝐵 𝑘,𝑀,𝑛 𝑘,𝑁,𝑛 𝑧,𝑘,𝜑,𝑛 Allowed substitution hints: 𝐴(𝑧,𝑘) 𝐵(𝑧) 𝑆(𝑧,𝑘,𝑛) 𝐹(𝑧,𝑘,𝑛) 𝐺(𝑧,𝑘,𝑛) 𝑀(𝑧) 𝑁(𝑧)

Proof of Theorem plymullem1 Dummy variable 𝑚 is distinct from all other variables.
