In this paper we applied the dynamic system theory to the measurement of the stability of the European process of convergence. In particular, Lyapunov’s exponents are used to verify the influence of political and economic decisions made during the creatio

In this paper, alternative non-parametric forecasting techniques are analysed, with emphasis placed on the difference between the reconstruction and learning approaches. The former is based on Takens’ Theorem, which recovers unknown dynamic properties of a system; it is appropriate in...
