A partire dagli studi sulla prospettiva degli artisti del Rinascimento, la geometria proiettiva si è sviluppata nei secoli successivi come disciplina autonoma che, oltre ad essere alla base della geometria algebrica classica, trova applicazioni in numerosi settori, dall’ingegneria alla computer vision, dall’architettura alla crittografia. La prima parte di questo testo contiene richiami, sintetici ma rigorosi, delle nozioni fondamentali di geometria proiettiva, in un linguaggio semplice e moderno. Ciò offre al lettore una rapida visione d’insieme della materia trattata e lo introduce alle tecniche e alle notazioni successivamente adoperate. Nella seconda parte sono presentati più di 200 problemi risolti, per molti dei quali si propongono più soluzioni alternative. Il livello di difficoltà è variabile: si spazia da esercizi di carattere calcolativo a problemi più impegnativi di carattere teorico, fino a veri e propri teoremi con dimostrazione guidata. La struttura del testo consente al lettore di utilizzare la risoluzione degli esercizi per impadronirsi delle nozioni e delle tecniche di base e per progredire nella conoscenza della materia fino allo studio di alcuni risultati classici.

This volume collects contributions from speakers at the INdAM Workshop “Birational Geometry and Moduli Spaces”, which was held in Rome on 11–15 June 2018. The workshop was devoted to the interplay between birational geometry and moduli spaces and the contributions of the volume reflect the same idea, focusing on both these areas and their interaction. In particular, the book includes both surveys and original papers on irreducible holomorphic symplectic manifolds, Severi varieties, degenerations of Calabi-Yau varieties, uniruled threefolds, toric Fano threefolds, mirror symmetry, canonical bundle formula, the Lefschetz principle, birational transformations, and deformations of diagrams of algebras. The intention is to disseminate the knowledge of advanced results and key techniques used to solve open problems. The book is intended for all advanced graduate students and researchers interested in the new research frontiers of birational geometry and moduli spaces.

Providing an overview of the state of the art on rationality questions in algebraic geometry, this volume gives an update on the most recent developments. It offers a comprehensive introduction to this fascinating topic, and will certainly become an essential reference for anybody working in the field. Rationality problems are of fundamental importance both in algebra and algebraic geometry. Historically, rationality problems motivated significant developments in the theory of abelian integrals, Riemann surfaces and the Abel-Jacobi map, among other areas, and they have strong links with modern notions such as moduli spaces, Hodge theory, algebraic cycles and derived categories. This text is aimed at researchers and graduate students in algebraic geometry.
