Mappings of Type Special Space of Sequences

الملخص EN

We give sufficient conditions on a special space of sequences defined by Mohamed and Bakery (2013) such that the finite rank operators are dense in the complete space of operators whose approximation numbers belong to this sequence space.

Hence, under a few conditions, every compact operator would be approximated by finite rank operators.

We apply it on the sequence space defined by Tripathy and Mahanta (2003).

Our results match those known for p -absolutely summable sequences of reals.
