Theorem smueqlem 16125

Description: Any element of a sequence multiplication only depends on the values of the argument sequences up to and including that point. (Contributed by Mario Carneiro, 20-Sep-2016.)

**Hypotheses**
Ref	Expression
smueq.a	⊢ (𝜑 → 𝐴 ⊆ ℕ₀)
smueq.b	⊢ (𝜑 → 𝐵 ⊆ ℕ₀)
smueq.n	⊢ (𝜑 → 𝑁 ∈ ℕ₀)
smueq.p	⊢ 𝑃 = seq0((𝑝 ∈ 𝒫 ℕ₀, 𝑚 ∈ ℕ₀ ↦ (𝑝 sadd {𝑛 ∈ ℕ₀ ∣ (𝑚 ∈ 𝐴 ∧ (𝑛 − 𝑚) ∈ 𝐵)})), (𝑛 ∈ ℕ₀ ↦ if(𝑛 = 0, ∅, (𝑛 − 1))))
smueq.q	⊢ 𝑄 = seq0((𝑝 ∈ 𝒫 ℕ₀, 𝑚 ∈ ℕ₀ ↦ (𝑝 sadd {𝑛 ∈ ℕ₀ ∣ (𝑚 ∈ 𝐴 ∧ (𝑛 − 𝑚) ∈ (𝐵 ∩ (0..^𝑁)))})), (𝑛 ∈ ℕ₀ ↦ if(𝑛 = 0, ∅, (𝑛 − 1))))

**Assertion**
Ref	Expression
smueqlem	⊢ (𝜑 → ((𝐴 smul 𝐵) ∩ (0..^𝑁)) = (((𝐴 ∩ (0..^𝑁)) smul (𝐵 ∩ (0..^𝑁))) ∩ (0..^𝑁)))

Distinct variable groups: 𝑚,𝑛,𝑝,𝐴 𝐵,𝑚,𝑛,𝑝 𝑚,𝑁,𝑛,𝑝 𝜑,𝑛 Allowed substitution hints: 𝜑(𝑚,𝑝) 𝑃(𝑚,𝑛,𝑝) 𝑄(𝑚,𝑛,𝑝)

Proof of Theorem smueqlem Dummy variables 𝑘 𝑖 𝑥 are mutually distinct and distinct from all other variables.
