报告摘要:A scattered operator is a bounded linear operator with at most countable spectrum. In this talk, we will talk about the history of scattered radical theory, and force on the algebra to B(H), the set of bound linear operators on Hilbert space. We prove that for any elementary operator on B(H), if the range of the elementary operator is contained in scattered operators, then the corresponding sum of multipliers is a compact operator. We also study some special classes of elementary operators, such as the elementary operators of length 2, higher order inner derivations and generalized inner derivation. At the same time, the multipliers of the corresponding elementary operators are characterized.
