On binary coproducts of frames. (English). Commentationes Mathematicae Universitatis Carolinae, vol. 33 (1992), issue 4, pp. 699-712
MSC: 06A15, 06A23, 18A20, 18A30, 54C10, 54D10, 54D30, 54D45 | MR 1240192 | Zbl 0824.54004
Keywords:
frame; binary coproduct; pushout; compactness; separatedness; continuous frame; closed homomorphism; $D(\kappa)$-frame
Summary:
The structure of binary coproducts in the category of frames is analyzed, and the results are then applied widely in the study of compactness, local compactness (continuous frames), separatedness, pushouts and closed frame homomorphisms.
