Theorem mbflimsup 23239

Description: The limit supremum of a sequence of measurable real-valued functions is measurable. (Contributed by Mario Carneiro, 7-Sep-2014.) (Revised by AV, 12-Sep-2020.)

**Hypotheses**
Ref	Expression
mbflimsup.1	⊢ 𝑍 = (ℤ_≥‘𝑀)
mbflimsup.2	⊢ 𝐺 = (𝑥 ∈ 𝐴 ↦ (lim sup‘(𝑛 ∈ 𝑍 ↦ 𝐵)))
mbflimsup.h	⊢ 𝐻 = (𝑚 ∈ ℝ ↦ sup((((𝑛 ∈ 𝑍 ↦ 𝐵) “ (𝑚[,)+∞)) ∩ ℝ^), ℝ^, < ))
mbflimsup.3	⊢ (𝜑 → 𝑀 ∈ ℤ)
mbflimsup.4	⊢ ((𝜑 ∧ 𝑥 ∈ 𝐴) → (lim sup‘(𝑛 ∈ 𝑍 ↦ 𝐵)) ∈ ℝ)
mbflimsup.5	⊢ ((𝜑 ∧ 𝑛 ∈ 𝑍) → (𝑥 ∈ 𝐴 ↦ 𝐵) ∈ MblFn)
mbflimsup.6	⊢ ((𝜑 ∧ (𝑛 ∈ 𝑍 ∧ 𝑥 ∈ 𝐴)) → 𝐵 ∈ ℝ)

**Assertion**
Ref	Expression
mbflimsup	⊢ (𝜑 → 𝐺 ∈ MblFn)

Distinct variable groups: 𝑥,𝑛,𝐴 𝐵,𝑚 𝜑,𝑛,𝑥 𝑚,𝑀 𝑚,𝑛,𝑥,𝑍 Allowed substitution hints: 𝜑(𝑚) 𝐴(𝑚) 𝐵(𝑥,𝑛) 𝐺(𝑥,𝑚,𝑛) 𝐻(𝑥,𝑚,𝑛) 𝑀(𝑥,𝑛)

Proof of Theorem mbflimsup Dummy variables 𝑖 𝑘 𝑦 𝑧 are mutually distinct and distinct from all other variables.
