本文研究了复对称算子的性质。特别地,我们证明了每一个具有性质(β)或(δ)的复对称算子是可分解的。此外,我们还证明了复对称算子T具有邓福德性质(C),且当且仅当其伴随子满足Weyl定理。
In this paper we study properties of complex symmetric operators. In particular, we prove that every complex symmetric operator having property (β) or (δ) is decomposable. Moreover, we show that complex symmetric operator T has Dunfordʼs property (C) and it satisfies Weylʼs theorem if and only if its adjoint does.
