Abstract: Abstract For a given space X let L ( X ) be the family of all compact subsets of X. A space X is dominated by the space M if X has an M-ordered compact… read more here.

Abstract: A topological space $X$ is strongly $D$ if for any neighbourhood assignment $\{U_x:x\in X\}$, there is a $D\subseteq X$ such that $\{U_x:x\in D\}$ covers $X$ and $D$ is locally finite in the topology generated by… read more here.
