Compact Operators on a Hilbert Space,ces are not bounded, and thus do not satisfy the hypotheses made previously. To circumvent this difficulty in part we apply the results to the inverse operators, which are not only bounded, but in addition are of a very special form. They are compact.作者: ARCH 時(shí)間: 2025-3-23 18:57
