MTH 517: Introduction to Algebraic Geometry (4)
Pre-requisites (Desirable): MTH 301, MTH 302, and MTH 401
Learning Objectives:
This course aims to provide an introduction to some of the basic objects and techniques and objects of algebraic geometry with minimal prerequisites. The main emphasis is on geometrical ideas and so most of the treatment will be over algebraically closed fields. Results from commutative algebra will introduced and proved as required and so no prior experience with commutative algebra will be assumed. After introducing the basic objects and techniques, they will be illustrated by application to the theory of algebraic curves.
Course Contents:
Closed subsets of affine space, coordinate rings, correspondence between ideals and closed subsets, affine varieties, regular maps, rational functions, Hilbert's nullstellensatz
Projective and quasi-projective varieties, regular and rational functions on projective varieties, products and maps of quasi-projective varieties
Dimension of varieties, examples and applications
Local ring of a point, tangent and cotangent space, local parameters, non-singular points and non-singular varieties
Birational maps, blowups, disingularization of curves
Intersection numbers for plane curves, divisors on curves, Bezout's theorem, Riemann-Roch theorem for curves, Residue theorem, Riemann-Hurwitz formula
