| Some strongly mixing invariant measures with full support are constructed for operators on metrizable and complete topological vector spaces which satisfy the Frequent Hypercyclicity Criterion, a sufficient condition for the existence of points x so that the hitting time set N(x,U) has positive lower density for any non-empty open set U. For unilateral backward shifts on sequence spaces, a slight modification shows that one can even obtain exact invariant measures. |
