[null,null,null,"Sommario/riassunto","The geometry of the hyperbolic plane has been an active and fascinating field of mathematical inquiry for most of the past two centuries. This book provides a self-contained introduction to the subject, suitable for third or fourth year undergraduates. The basic approach taken is to define hyperbolic lines and develop a natural group of transformations preserving hyperbolic lines, and then study hyperbolic geometry as those quantities invariant under this group of transformations. Topics covered include the upper half-plane model of the hyperbolic plane, Möbius transformations, the general Möbius group, and their subgroups preserving the upper half-plane, hyperbolic arc-length and distance as quantities invariant under these subgroups, the Poincaré disc model, convex subsets of the hyperbolic plane, hyperbolic area, the Gauss-Bonnet formula and its applications. This updated second edition also features: an expanded discussion of planar models of the hyperbolic plane arising from complex analysis; the hyperboloid model of the hyperbolic plane; brief discussion of generalizations to higher dimensions; many new exercises. The style and level of the book, which assumes few mathematical prerequisites, make it an ideal introduction to this subject and provides the reader with a firm grasp of the concepts and techniques of this beautiful part of the mathematical landscape. ."]

[null,null,null,"Sommario/riassunto","Nationalism is on the rise across the Western world, serving as a rallying cry for voters angry at the unacknowledged failures of globalization that has dominated politics and economics since the end of the Cold War. In After Nationalism, Samuel Goldman trains a sympathetic but skeptical eye on the trend, highlighting the deep challenges that face any contemporary effort to revive social cohesion at the national level.Noting the obstacles standing in the way of basing any unifying political project on a singular vision of national identity, Goldman highlights three pillars of mid-twentieth-century nationalism, all of which are absent today: the social dominance of Protestant Christianity, the absorption of European immigrants in a broader white identity, and the defense of democracy abroad. Most of today's nationalists fail to recognize these necessary underpinnings of any renewed nationalism, or the potentially troubling consequences that they would engender.To secure the general welfare in a new century, the future of American unity lies not in monolithic nationalism. Rather, "]
