Theorem lgamucov 26989

Description: The 𝑈 regions used in the proof of lgamgulm 26986 have interiors which cover the entire domain of the Gamma function. (Contributed by Mario Carneiro, 6-Jul-2017.)

**Hypotheses**
Ref	Expression
lgamucov.u	⊢ 𝑈 = {𝑥 ∈ ℂ ∣ ((abs‘𝑥) ≤ 𝑟 ∧ ∀𝑘 ∈ ℕ₀ (1 / 𝑟) ≤ (abs‘(𝑥 + 𝑘)))}
lgamucov.a	⊢ (𝜑 → 𝐴 ∈ (ℂ ∖ (ℤ ∖ ℕ)))
lgamucov.j	⊢ 𝐽 = (TopOpen‘ℂ_fld)

**Assertion**
Ref	Expression
lgamucov	⊢ (𝜑 → ∃𝑟 ∈ ℕ 𝐴 ∈ ((int‘𝐽)‘𝑈))

Distinct variable groups: 𝑘,𝑟,𝑥,𝐴 𝜑,𝑘,𝑟,𝑥 Allowed substitution hints: 𝑈(𝑥,𝑘,𝑟) 𝐽(𝑥,𝑘,𝑟)

Proof of Theorem lgamucov Dummy variable 𝑎 is distinct from all other variables.
