Abstract:
We give an operator theoretic proof of the following result of D. G. Tacon: Theorem. If $\{ {T_n}\}$ is a sequence of bounded linear operators in a complex infinite dimensional Hilbert space with the property that for every bounded sequence $\{ {x_n}\}$ there exists a positive integer k such that the sequence $\{ {T_k}{x_n}\} _{n = 1}^\infty$ has a convergent subsequence, then there exists k such that ${T_k}$ is a compact operator.References
