Controllability is an important property of a control system and plays a crucial role in many control problems, such as stabilization of unstable systems by feedback, or optimal control. Controllability and observability are dual aspects of the same problem.
Statements of Financial Accounting Standards No. 133, Accounting for Derivative Instruments and Hedging Activities, commonly known as FAS 133, is an accounting standard issued in June 1998 by the Financial Accounting Standards Board (FASB) that requires companies to measure all assets and liabilities on their balance sheet at “fair value”.

A special case of this result appeared first in 1963 in a paper by Elmer G. Gilbert, [1] and was later expanded to the current PBH test with contributions by Vasile M. Popov in 1966, [3] [4] Vitold Belevitch in 1968, [5] and Malo Hautus in 1969, [5] who emphasized its applicability in proving results for linear time-invariant systems.

Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. In control theory, the observability and controllability of a linear system are mathematical duals.
We can see that is a symmetric matrix, therefore, so is .. We can use again the fact that, if is stable (all its eigenvalues have negative real part) to show that is unique.
The ordinary Lyapunov function is used to test whether a dynamical system is (Lyapunov) stable or (more restrictively) asymptotically stable. Lyapunov stability means that if the system starts in a state x ≠ 0 {\displaystyle x\neq 0} in some domain D , then the state will remain in D for all time.
