Theorem xrhmeo 24219

Description: The bijection from [-1, 1] to the extended reals is an order isomorphism and a homeomorphism. (Contributed by Mario Carneiro, 9-Sep-2015.)

Ref	Expression
xrhmeo.f	⊢ 𝐹 = (𝑥 ∈ (0[,]1) ↦ if(𝑥 = 1, +∞, (𝑥 / (1 − 𝑥))))
xrhmeo.g	⊢ 𝐺 = (𝑦 ∈ (-1[,]1) ↦ if(0 ≤ 𝑦, (𝐹‘𝑦), -_𝑒(𝐹‘-𝑦)))
xrhmeo.j	⊢ 𝐽 = (TopOpen‘ℂ_fld)

**Assertion**
Ref	Expression
xrhmeo	⊢ (𝐺 Isom < , < ((-1[,]1), ℝ^*) ∧ 𝐺 ∈ ((𝐽 ↾_t (-1[,]1))Homeo(ordTop‘ ≤ )))

Distinct variable groups: 𝑥,𝑦 𝑦,𝐹 𝑥,𝐽,𝑦 Allowed substitution hints: 𝐹(𝑥) 𝐺(𝑥,𝑦)
