Query: Locally upper bounded poset-valued maps and stratifiable spaces   In this paper, we characterize stratifiable (or semi-stratifiable) spaces,
and monotonically countably paracompact (or monotonically countably
metacompact) spaces by expansions of locally upper bounded semi-continuous
poset-valued maps. These extend earlier results for real-valued Locally bounded
functions.
