Summary:The optimal control problem in a finite time horizon with an
indefinite quadratic cost function for a linear system subject to
multiplicative noise on both the state and control can be solved via a
constrained matrix differential Riccati equation. In this paper, we
provide general necessary and sufficient conditions for the solvability
of this generalized differential Riccati equation. Furthermore, its
asymptotic behavior is investigated along with its connection to the
generalized algebraic Riccati equation associated with the linear
quadratic control problem in finite time horizon. Examples are presented
to illustrate the results established
