# On S-independence and Hansson’s external independence

Research output: Contribution to journalArticle

### Abstract

This paper provides a generalized characterization of the family of independence conditions which are equivalent to independence of irrelevant alternatives by proposing a pair-based refinement of $$\mathcal {S}$$S-independence. Equipped with the new result, the relation between external independence conditions and independence of irrelevant alternatives is explored.
