A note on $G_{\delta}$ ideals of compact sets

Comment.Math.Univ.Carolin. 50,4 (2009) 569-573.

Abstract:Solecki has shown that a broad natural class of $G_{\delta}$ ideals of compact sets can be represented through the ideal of nowhere dense subsets of a closed subset of the hyperspace of compact sets. In this note we show that the closed subset in this representation can be taken to be closed upwards.

Keywords: descriptive set theory, ideals of compact sets
