The solvability of the regulator equation for a general nonlinear system is discussed in this paper by using geometric method. The `feedback' part of the regulator equation, ...
This paper investigates the problem of causal observability of the states and unknown inputs of nonlinear time-delay systems. Using the theory of non-commutative rings, the nonline...

We study the symmetries of periodic solutions from Hopf bifurcation in systems with finite abelian symmetries. Our main result, the Abelian Hopf H mod K Theorem, gives necessary a...
Uncertainty arises in preference aggregation in several ways. There may, for example, be uncertainty in the votes or the voting rule. Such uncertainty can introduce computational ...
The computer systems for the decision-making must provide in a synthetic and simple way the necessary elements to the decisionmaker. That is why, it is indispensable to build Compu...
