    Hyperstonean locales

    Hyperstonean locales can be defined as Stonean locales that admit sufficiently many normal valuations.

    Assuming the axiom of choice, Stonean locales are spatial, so the category of hyperstonean locales is equivalent to the category of hyperstonean spaces.

    Hyperstonean cover

    Given a compact Hausdorff space XX, its hyperstonean cover is defined as a continuous map of compact Hausdorff spaces

    hXXhX \to X

    that under the Gelfand duality corresponds to the canonical inclusion C(X)C(X) **C(X)\to C(X)^{**} into the double dual.

    The hyperstonean cover of a compact Hausdorff space is introduced in
