Query: On the similarity of complex symmetric operators to perturbations of
  restrictions of normal operators   In this paper we consider a problem of the similarity of complex symmetric
operators to perturbations of restrictions of normal operators. For a subclass
of cyclic complex symmetric operators in a finite-dimensional Hilbert space we
prove the similarity to rank-one perturbations of restrictions of normal
operators. The main tools are a truncated moment problem in $\mathbb{C}$, and
some objects similar to objects from the theory of spectral problems for Jacobi
matrices.
