摘要：
We study in this paper the infinite-dimensional orthogonal Lie algebra O-C which consists of all bounded linear operators Ton a separable, infinite-dimensional, complex Hilbert space Hsatisfying CTC=-T*, where C is a conjugation on H. By employing results from the theory of complex symmetric operators and skew-symmetric operators, we determine the Lie ideals of O-C and their dual spaces. We study derivations of O-C and determine their spectra. These results complete some results of P. de la Harpe and provide interesting contrasts between O-C and the algebra B(H) of all bounded linear operators on H. (C) 2020 Elsevier Inc.
