The paper is concerned with the boundary controllability of entropy weak solutions to hyperbolic systems of conservation laws. We prove a general result on the asymptotic stabilization of a system near a constant state. On the other hand, we give an example showing that exact controllability in finite time cannot be achieved, in general.

By using concrete scenarios, we present and discuss a new concept of probabilistic Self-Stabilization in Distributed Systems.

Dijkstra’s concept of self-stabilization assumes that faults can only affect the variables of a program. We study the notion of self-stabilization if faults can also affect (i.e., augment) the program code of a system. A code stabilizing system automatically recovers from (almost) arbitrary perturbations of its program code. We prove some lower bounds for code stabilizing systems and argue that...

In this paper, a fractional order economic system is studied. An active control technique is applied to control chaos in this system. The stabilization of equilibria is obtained by both theoretical analysis and the simulation result. The numerical simulations, via the improved Adams–Bashforth algorithm, show the effectiveness of the proposed controller.

Indeed, one of the …rst lessons one learns from studying a variety of hypothetical models is that the problem of economic stabilization is, even in principle, an extremely intricate one, and that a much more thorough investigation of both theoretical principles and empirical relationships would be needed before detailed policy recommendations could be justi…ed.”A.

The interaction of monetary and fiscal policies is a crucial issue in a highly integrated economic area as the EU. In this paper we study policy cooperation. In particular, we focus on how coalitions among policy-makers are formed and what are their effects on the stabilization of output and price.
