Hashimoto topologies and quasi-continuous maps
Hereditarily normal Katětov spaces and extending of usco mappings
Several classes of hereditarily normal spaces are characterized in terms of extending upper semi-continuous compact-valued mappings. The case of controlled extensions is considered as well. Applications are obtained for real-valued semi-continuous functions.
