Theorem climmptf 46343
Description: Exhibit a function 𝐺 with the same convergence properties as the not-quite-function 𝐹. (Contributed by Glauco Siliprandi, 23-Oct-2021.)
Hypotheses
Ref Expression
climmptf.k 𝑘𝐹
climmptf.m (𝜑𝑀 ∈ ℤ)
climmptf.f (𝜑𝐹𝑉)
climmptf.z 𝑍 = (ℤ𝑀)
climmptf.g 𝐺 = (𝑘𝑍 ↦ (𝐹𝑘))
Assertion
Ref Expression
climmptf (𝜑 → (𝐹𝐴𝐺𝐴))
Distinct variable group:   𝑘,𝑍
Allowed substitution hints:   𝜑(𝑘)   𝐴(𝑘)   𝐹(𝑘)   𝐺(𝑘)   𝑀(𝑘)   𝑉(𝑘)

Proof of Theorem climmptf
Dummy variable 𝑗 is distinct from all other variables.
