An embedding in the Fell topology

Published 18 Feb 2014 in math.GN | (1402.4282v1)

Abstract: It is shown that if a $T_2$ topological space contains an uncountable closed discrete set, then $\omega_1 \times (\omega_1 + 1)$ embeds as a closed subspace of $(CL(X),\tau_F)$, the hyperspace of nonempty closed subsets of $X$ equipped with the Fell topology.
