Hypotheses
Ref Expression
zprod.1 𝑍 = (ℤ𝑀)
zprod.2 (𝜑𝑀 ∈ ℤ)
zprod.3 (𝜑 → ∃𝑛𝑍𝑦(𝑦 ≠ 0 ∧ seq𝑛( · , 𝐹) ⇝ 𝑦))
zprod.4 (𝜑𝐴𝑍)
zprod.5 ((𝜑𝑘𝑍) → (𝐹𝑘) = if(𝑘𝐴, 𝐵, 1))
zprod.6 ((𝜑𝑘𝐴) → 𝐵 ∈ ℂ)
Assertion
Ref Expression
zprod (𝜑 → ∏𝑘𝐴 𝐵 = ( ⇝ ‘seq𝑀( · , 𝐹)))
Distinct variable groups:   𝐴,𝑘,𝑛,𝑦   𝐵,𝑛,𝑦   𝑘,𝐹   𝑘,𝑛,𝜑,𝑦   𝑘,𝑀,𝑦   𝜑,𝑛,𝑦   𝑛,𝑍
Allowed substitution hints:   𝐵(𝑘)   𝐹(𝑦,𝑛)   𝑀(𝑛)   𝑍(𝑦,𝑘)

Proof of Theorem zprod
Dummy variables 𝑓 𝑔 𝑖 𝑗 𝑚 𝑥 𝑧 are mutually distinct and distinct from all other variables.
