  • Caliber, precaliber, and the shanin number of hyperspaces
    Ruzinazar Beshimov (pp. 22-27)

    • Abstract.

    In the paper, we investigate relationships between cardinal invariants of a topolo- gical space X and its hyperspace exp X: We prove that the hyperspace construction preserves caliber, precaliber, and the Shanin numbers.

    Keywords:

    cardinal, topological space, caliber, precaliber, the Shanin number.
