Query: Commutativity of Systems with their Feedback Conjugates   After introducing commutativity concept and summarizing the relevant
literature, this work is focused on the commutativity of feedback conjugates.
It is already known that a linear time-varying differential system describing a
single input-single output dynamical system is always commutative with its
constant gain feedback pairs. In this article, it is proven that among the
time-varying feedback conjugates of a linear time-varying system, constant
feedback conjugates are the only commutative feedback pairs and any of the
time-varying feedback conjugates cannot constitutes a commutative pair of a
linear time-varying system.
