Algebraic spaces and stacks

Olsson, Martin

Algebraic spaces and stacks - Rhode Island : American Mathematical Society, 2016 - xi, 298p. : illustrations ; 26 cm. - American Mathematical Society colloquium publications ; volume 62 .

Includes bibliographical references (pages 291-293) and index.

This book is an introduction to the theory of algebraic spaces and stacks intended for graduate students and researchers familiar with algebraic geometry at the level of a first-year graduate course. The first several chapters are devoted to background material including chapters on Grothendieck topologies, descent, and fibered categories. Following this, the theory of algebraic spaces and stacks is developed. The last three chapters discuss more advanced topics including the Keel-Mori theorem on the existence of coarse moduli spaces, gerbes and Brauer groups, and various moduli stacks of curves. Numerous exercises are included in each chapter ranging from routine verifications to more difficult problems, and a glossary of necessary category theory is included as an appendix.

Graduate students and research mathematicians interested in algebraic spaces and stacks.
