Theorem broucube 37062

Description: Brouwer - or as Kulpa calls it, "Bohl-Brouwer" - fixed point theorem for the unit cube. Theorem on [Kulpa] p. 548. (Contributed by Brendan Leahy, 21-Aug-2020.)

**Hypotheses**
Ref	Expression
poimir.0	⊢ (𝜑 → 𝑁 ∈ ℕ)
poimir.i	⊢ 𝐼 = ((0[,]1) ↑_m (1...𝑁))
poimir.r	⊢ 𝑅 = (∏_t‘((1...𝑁) × {(topGen‘ran (,))}))
broucube.1	⊢ (𝜑 → 𝐹 ∈ ((𝑅 ↾_t 𝐼) Cn (𝑅 ↾_t 𝐼)))

**Assertion**
Ref	Expression
broucube	⊢ (𝜑 → ∃𝑐 ∈ 𝐼 𝑐 = (𝐹‘𝑐))

Distinct variable groups: 𝜑,𝑐 𝐹,𝑐 𝐼,𝑐 𝑁,𝑐 𝑅,𝑐

Proof of Theorem broucube Dummy variables 𝑛 𝑥 𝑧 are mutually distinct and distinct from all other variables.
