True preimages of compact or separable sets for functional analysts

Comment.Math.Univ.Carolin. 61,1 (2020) 69-82.

Abstract:We discuss various results on the existence of `true' preimages under continuous open maps between $F$-spaces, $F$-lattices and some other spaces. The aim of the paper is to provide accessible proofs of this sort of results for functional-analysts.

Keywords: preimage; open map; complete metric space; $F$-space; $F$-lattice; compact set; uniformly open map; surpositive operator; lower semicontinuous set-valued map
