ErgodicSMul

(G : Type u_1) → (α : Type u_2) → [SMul G α] → {x : MeasurableSpace α} → MeasureTheory.Measure α → Prop

A group action of G on a space α with measure μ is called ergodic, if for any (null) measurable set s, if it is a.e.-invariant under each scalar multiplication (g • ·), g : G, then it is either null or conull.
