Event description: 
Let X be a K3 surface. Consider a finitely supported probability measure μμ on Aut(X) such that Γμ=⟨Supp(μ)⟩<Aut(X)Γμ=⟨Supp(μ)⟩<Aut(X) is non-elementary. We do not assume that ΓμΓμ contains any parabolic elements. We study and classify hyperbolic ergodic μμ-stationary probability measures on X.
