The teaching assistant is Tom Ducat <>.
I will be away Fri 18th Oct and some days in Weeks 4, and I will
assign some alternative work.

The pdf and source TeX file of the book is available online
(unlinked, and currently without the graphics). If you need
the link, please let me know. I hope that one or two of the
students can help putting the graphics back into the TeX file.

Assignment sheets:

There will be approximately 6 compulsory assignments counting for 30\%
of the credit.
Assignment 1, deadline TBA
first draft of Assignment 2, deadline TBA

Prerequisites and suitability for 3rd year MMathers

The course uses basic definitions from most 1st and 2nd year courses, including algebra, geometry, analysis. More than technical prerequisites, the main requirement is the sophistication to work simultaneously with ideas from several areas of mathematics: projective geometry, rings and fields, basic topology and analysis. I would expect the course to be harder than most for third year students, but not impossible for those who are well motivated and can rise to a challenge. The reward consists of access to 4th year and MSc/PhD courses and projects in algebraic geometry.

MA505 Algebraic geometry

Not on this year. I will eventually put up some information about the graduate course MA610 (not for credit).

The PYDC entry is here.   This is a first introduction to algebraic geometry at the MSc level. One of the central topics is the relation between the commutative algebra of graded rings and the geometry of projective varieties and singularities. The emphasis is on concrete examples of curves, surfaces, projective arieties and singularities, as illustrated in my Park City lecture notes [Chapters] and in the book in progress [More Chapters]. Technical foundational material, for example on commutative algebra and affine schemes, on sheaves and coherent cohomology, will be introduced as required, without detailed proofs. Students may wish to study more material in a parallel self-help seminar (I can try to arrange exam credit for this as necessary).


This is a second course in Algebraic Geometry, and it assumes background knowledge at the level of the undergraduate course MA4A5 Algebraic Geometry or the material of [UAG] or the first two chapters of Shafarevich, Basic algebraic geometry.

Timetable for 2006-07, Term 2:

Tue 2-3, B3.01
Thu 10-11, B3.01
Fri 11-12, B3.01

Several beginning postgraduates and visiting students will be studying the subject at some level, and should take keep a look-out for seminars at Warwick and elsewhere. (e.g. the COW and Calf that meets in Warwick, Oxford, London, Bath, etc. Google "COW seminar").
