Domain-specific

• Adherent point
  • An adherent or closure point may lie outside the set and differs from an accumulation point because the neighborhood intersection can be the point itself; nets or filters characterize the same relation under standard topology.
• Fort space
  • … subspace, cofinite neighborhoods, unique accumulation point, compactness and T1 and Hausdorff properties, one-point-compactification equivalence and modified and Fortissimo variants are explicit. to An applied instance preserves the invariant under changed notation, scale, dataset, jurisdiction, or implementation..
• Sequentially compact space
  • For example, the distinction between constitutive identity and a convenient observable transfers from A closed bounded subset of Euclidean space is sequentially compact by Bolzano–Weierstrass. to A proof checks metrizability or first-countability before substituting sequential compactness for compactness..
