This book gives a brief survey of the theory of multidimensional (multivariate), weakly stationary time series, with emphasis on dimension reduction and prediction. Understanding the covered material requires a certain mathematical maturity, a degree of knowledge in probability theory, linear algebra, and also in real, complex and functional analysis. For this, the cited literature and the Appendix contain all necessary material. The main tools of the book include harmonic analysis, some abstract algebra, and state space methods: linear time-invariant filters, factorization of rational spectral densities, and methods that reduce the rank of the spectral density matrix. * Serves to find analogies between classical results (Cramer, Wold, Kolmogorov, Wiener, Kalman, Rozanov) and up-to-date methods for dimension reduction in multidimensional time series. * Provides a unified treatment for time and frequency domain inferences by using machinery of complex and harmonic analysis, spectral and Smith--McMillan decompositions. Establishes analogies between the time and frequency domain notions and calculations. * Discusses the Wold's decomposition and the Kolmogorov's classification together, by distinguishing between different types of singularities. Understanding the remote past helps us to characterize the ideal situation where there is a regular part at present. Examples and constructions are also given. * Establishes a common outline structure for the state space models, prediction, and innovation algorithms with unified notions and principles, which is applicable to real-life high frequency time series. It is an ideal companion for graduate students studying the theory of multivariate time series and researchers working in this field.

Economic sanctions are instruments of foreign policy. However, they can also affect legal relations between private parties - principally in contract. In such cases, the court or arbitration tribunal seized must decide whether to give effect to the economic sanction in question. Private international law functions as a 'filter', transmitting economic sanctions that originate in public law to the realm of private law. The aim of this book is to examine how private international law rules can influence the enforcement of economic sanctions and their related foreign policy objectives. A coherent EU foreign policy position - in addition to promoting legal certainty and predictability - would presuppose a uniform approach not only concerning the economic sanctions of the EU, but also with regard to the restrictive measures imposed by third countries. However, if we examine in detail the application of economic sanctions by Member States' courts and arbitral tribunals, we find a somewhat different picture. This book argues that this can be explained in part by the divergence of private international law approaches in the Member States.
