Let $H$ be an infinite dimensional separable Hilbert space over $\mathbb{C}$

Let $\{h_n\}_{n \in \mathbb{N}} \in H$ be a sequence of linearly independent vectors in $H$

Let $$ V= \bigcap_{n=1}^\infty \overline{ \operatorname{ span }} \{h_m\}_{m \geq n} $$

Is it possible that $$ \dim V=1 $$

Thanks

    $\begingroup$ What is $V$ if $h_n=e_0+e_n$ for $n \geq 1$? $\endgroup$ Commented Oct 8, 2019 at 20:54

    $\begingroup$ No shame: easy-to-answer questions are the best! :) Seriously, in some way easy-to-answer-by-experts are the best questions for non-experts to ask. I guess in a perfect world that would be what experts would be for. :) $\endgroup$ Commented Oct 8, 2019 at 21:57
