QUASI-INVARIANT STATES FOR COMPACT GROUP ACTIONS: REDUCTION TO NORMAL SUBGROUPS AND QUOTIENTS

Abstract We establish a structural decomposition theorem for quasi-invariant states under compact group actions. For a compact group G , a closed normal subgroup H and an action α : G → Aut ( A ) $\alpha :G\to \mathrm {Aut}(\mathfrak {A})$ alpha colon upper G right arrow upper A...
