In this case, a matrix-valued symmetric negative imaginary transfer function G(s): C → Cm×m is identical to an operator-valued CSNI transfer function defined on a finite dimensional Hilbert space. A ...

Let K=ℚ−d be an imaginary quadratic number field of class number 1 and O𝕂 its ring of integers. We study a family of Hecke L-functions associated to angular characters on the non-zero ideals of O𝕂.
