Global economics governance in the post-crisis world

The Great Crisis has made it clear once again that avoiding the derailment of globalization of trade and finance and the protecting the globe from fragmentation call for enhanced global cooperation and an efficient, flexible and coherent system of global governance. Three interconnected levels (national, regional, and global) comprise the system of global governance. This paper is dealing with some of the main issues of global economic governance in the post-crisis world. It reveals that the turbulence and the distress of the world of the early 21st century have deeper roots and broader sources than the crisis. Global governance therefore has to respond much broader set of challenges in comprehensive framework and long term perspective

Local Nash Realizations

In this paper we investigate realization theory of a class of non-linear systems, called Nash systems. Nash systems are non-linear systems whose vector fields and readout maps are analytic semi-algebraic functions. In this paper we will present a characterization of minimality in terms of observability and reachability and show that minimal Nash systems are isomorphic. The results are local in nature, i.e. they hold only for small time intervals. The hope is that the presented results can be extended to hold globally.Comment: 8 pages, extended conference pape
