The sigma-ideal of path-law candidates failing a prescribed countable/atomless test. A finite atomless measure dominating any countable list of such tests is constructed from the existing finite-measure representative of an s-finite measure.

    Source documentation

    A candidate family is small when one countable set and one finite atomless test measure rule out every member. This is the manuscript's small-set ideal.
