摘要
Given a conjugation C on a separable complex Hilbert space H, a bounded linear operator T on H is said to be C-symmetric if CTC = T*. In this paper, we study some nonlinear preserving problems concerning C-symmetric operators and diagonal operators, as a result, we also describe those nonlinear preservers of the lattice of invariant subspaces.
