    Sieves and completeness properties (English)
    0 references
    Standard methods are used to characterize certain classes of spaces as images of (completely) metrizable spaces under certain upper semicontinuous compact-valued mappings. The authors characterize in this way spaces of point-countable type, sieve-complete spaces and first-countable sieve-complete spaces.
