affine extensions of functions - Opis:
- Let A be a closed Gδ-subset of a normal space X. We prove that every function ƒ0 : A → R with a closed graph can be extended to a function ƒ: X → R with a closed graph, too. This is a consequence of a more general result which gives an affine and constructive method of obtaining such extensions.
