Ellis groups of quasi-factors of minimal flows

A quasi-factor of a minimal flow is a minimal subset of the induced flow on the space of closed subsets. We study a particular kind of quasi-factor (a "joining" quasi-factor) using the Galois theory of minimal flows. We also investigate the relation between factors and quasi-factors.
