I will introduce the notion of Kurosh rank for subgroups of
free products. This rank satisfies the Howson property, i.e. the
intersection of two subgroups of finite Kurosh rank has finite Kurosh rank.
I will present a version of the Strengthened Hanna Neumann inequality in
the case of free products of right-orderable groups. Joint work with A.
Martino and I. Schwabrow.
