An analytical characterization of effective and of irreducible groups inducing cone orderings
Group majorization for a closed subgroup \(G\) of an orthogonal group is a relation on vectors that \(y\) lies in the convex hull of the orbit of \(x\); permutation groups gives classical majorization. For group majorizations which may be represented as preorderings, the properties of effectiveness and irreducibility are characterized here.
