Query: Feedback Stabilization over Commutative Rings with no
  Right-/Left-Coprime Factorizations   Anantharam showed in 1985 the existence of a model in which some stabilizable
plants do not have its right-/left-coprime factorizations. In this paper, we
give a condition of the nonexistence of the right-/left-coprime factorizations
of stabilizable plants as a generalization of Anantharam's result. As examples
of the models which satisfy the condition, we present two models. We illustrate
the construction of a stabilizing controller of stabilizable single-input
single-output plants of such models.
