Definition. We define struct_c_T1_topology to be λX ⇒ struct_cX ∧ unpack_c_oX(λX' Open ⇒ Open(λx ⇒ x∈X') ∧ (∀U V : set → prop, OpenU → OpenV → Open(λx ⇒ Ux ∧ Ux)) ∧ (∀C : (set → prop) → prop, (∀U : set → prop, CU → OpenU) → Open(λx ⇒ ∃U : set → prop, CU ∧ Ux)) ∧ (∀a b ∈ X', a ≠ b → ∃U : set → prop, OpenU ∧ exactly1of2(Ua)(Ub))) of type set → prop.
