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

Logic 2018-07-04 v1

Abstract

Solecki has shown that a broad natural class of GδG_{\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.
