Sommario/riassunto

The book incorporates research papers and surveys written by participants ofan International Scientific Programme on Approximation Theory jointly supervised by Institute for Constructive Mathematics of University of South Florida at Tampa, USA and the Euler International Mathematical Instituteat St. Petersburg, Russia. The aim of the Programme was to present new developments in Constructive Approximation Theory. The topics of the papers are: asymptotic behaviour of orthogonal polynomials, rational approximation of classical functions, quadrature formulas, theory of n-widths, nonlinear approximation in Hardy algebras,numerical results on best polynomial approximations, wavelet analysis.

Sommario/riassunto

Militant Islam provides a sociological framework for understanding the rise and character of recent Islamic militancy. It takes a systematic approach to the phenomenon and includes analysis of cases from around the world, comparisons with militancy in other religions, and their causes and consequences.The sociological concepts and theories examined in the book include those associated with social closure, social movements, nationalism, risk, fear and 'de-civilising'. These are



applied within three main themes; characteristics of militant Islam, multi-layered causes and the consequenc
