An Undergraduate Primer in Algebraic Geometry

by Ciro Ciliberto

Overview

This book consists of two parts. The first is devoted to an introduction to basic concepts in algebraic geometry: affine and projective varieties, some of their main attributes and examples. The second part is devoted to the theory of curves: local properties, affine and projective plane curves, resolution of singularities, linear equivalence of divisors and linear series, Riemann–Roch and Riemann–Hurwitz Theorems.

The approach in this book is purely algebraic. The main tool is commutative algebra, from which the needed results are recalled, in most cases with proofs. The prerequisites consist of the knowledge of basics in affine and projective geometry, basic algebraic concepts regarding rings, modules, fields, linear algebra, basic notions in the theory of categories, and some elementary point–set topology.

This book can be used as a textbook for an undergraduate course in algebraic geometry. The users of the book are not necessarily intended to become algebraic geometers but may be interested students or researchers who want to have a first smattering in the topic.

The book contains several exercises, in which there are more examples and parts of the theory that are not fully developed in the text. Of some exercises, there are solutions at the end of each chapter.

Editorial Reviews

The text is fairly self-contained … . The clear exposition and numerous exercises also make the text suitable for self-study … . The text is thorough and clearly written, and the numerous exercises do indeed give the reader an algebraic primer to algebraic geometry.” (Kelly Jabbusch, Mathematical Reviews, June, 2022)

“New concepts in algebra that one needs, in order to understand the content of the book, are introduced … . I find this feature as an asset of the present book. … the present book is a valuable introduction to algebraic geometry which is nicely written … and a pleasure to read. It can be recommended as a first book for undergraduate courses devoted to algebraic geometry, and also as a supplementary source for standard courses devoted to algebraic geometry.” (Piotr Pokora, zbMATH 1471.14001, 2021)
