摘要:
We prove in this paper that if (T-n) is a hereditarily hypercyclic sequence of continuous linear mappings between two topological vector spaces X and Y, where Y is metrizable, then there is an infinite-dimensional linear submanifold M of X such that each non-zero vector of M is hypercyclic for (T-n). If, in addition, X is metrizable and separable and (T-n) is densely hereditarily hypercyclic, then M can be chosen dense.
