Query: Linear Algebraic Properties for Jordan Models of $C_{0}$-operators
  relative to multiply connected domains   We study $C_{0}$-operators relative to a multiply connected domain using a
substitute of the characteristic function. This method allows us to prove
certain relations between the Jordan model of an operator and that of its
restriction to an invariant subspace.
