Reading course at JGU, Mainz.
A spectacular blow up


Dino Festi

Davide Cesare Veniani

Time and venue

The lectures are given on Thursdays, 12 -- 14.

The lectures are held in Room 04.516.

Aims of the course

The course is intended as a starting course in Algebraic Geometry and it is aimed to bachelor and master students who are familiar with commutative algebra.

During the course we will follow Robin Hartshorne's book `Algebraic Geometry'.

The aim of the course is to study in detail the first two chapters of the book, discussing the proofs of the results and solving, or trying to solve, the exercises.

Once solved, the solutions of the exercise will be published on this website, for future memory.

The course is also a place where to discuss the content of Manfred Lehn's course `Invariant theory'. During the course the students will be welcome to ask questions about Lehn's classes. For this reason Lehn's student are particularly encouraged to follow the course.


We shall follow Hartshorne's `Algebraic Geometry' [HAG], the first 2 chapters.

The curious student may also read `The red book of varieties and schemes', by Mumford [MVS].

For reference to commutative algebra, we suggest the book `Introduction to Commutative Algebra', by Atiyah--MacDonald [AM], and/or `Commutative Algebra with a view toward Algebraic Geometry' by Eisenbud [EIS].
