Local and global properties of spaces of minimal usco maps
In this paper, we study an interplay between local and global properties of
spaces of minimal usco maps equipped with the topology of uniform convergence
on compact sets. In particular, for each locally compact space $X$ and metric
space $Y$, we characterize the space of minimal usco maps from $X$ to $Y$,
satisfying one of the following properties: (i) compact, (ii) locally compact,
(iii) $\sigma$-compact, (iv) locally $\sigma$-compact, (v) metrizable, (vi)
ccc, (vii) locally ccc, where in the last two items we additionally assumed
that $Y$ is separable and non-discrete. Some of the aforementioned results
complement ones of \v{L}ubica Hol\'a and Du\v{s}an Hol\'y. Also, we obtain
analogical characterizations for spaces of minimal cusco maps.
