separation theorem[‚sep·ə′rā·shən ‚thir·əm] (control systems) A theorem in optimal control theory which states that the solution to the linear quadratic Gaussian problem separates into the optimal deterministic controller (that is, the optimal controller for the corresponding problem without noise) in which the state used is obtained as the output of an optimal state estimator. Separation theorem
Separation theoremTheory that the value of an investment to an individual is not dependent on consumption preferences. That is, investors will want to accept or reject the same investment projects by using the NPV rule, regardless of personal preference.Separation TheoremAn economic theory stating that the investment decisions of a firm are independent from the firm's owner's wishes. The Separation Theorem states that the productive value of a firm's management neither affects nor is affected by the owner's business decisions. As a result, the performance of a firm's investments has no relation to how they are financed, whether by stock, debt, or cash. The theorem was devised by economist Irving Fisher.
