On Aumann's theorem that the circle does not admit a mean
On --open sets and --continuous functions.
On Baire approximations of normal integrands
On Baire isomorphisms of non-metrizable compacta
On barely continuous functions.
On barycentrically soft compacta
On binary coproducts of frames
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.
