... maps are continuous, then U × Y ∩ X × V = U × V is open. Consequently, ifUα and Vα are open in X and Y for each α, then Uα × Vα is open for each α and so ∪ Uα × Vα is open. It follows that each open set in the product topology for X × Y is also open in the unspecified topology, which is what we we ...

... of increasing open subsets of X becomes stationary. Equivalently, the set of closed subsets satisfy the descending chain condition. (ii) A nonempty subset Y of X is irreducible if it cannot be expressed as the union Y = Y1 ∪ Y2 of two proper subsets, each one of which is closed in Y . (iii) An irred ...
