Summary  Algebraic geometry studies geometric objects defined algebraically. It is a classical subject with a modern face that studies geometric spaces defined by polynomial equations in several variables.
Besides providing crucial techniques and examples to many other areas of geometry and topology, recent decades have seen remarkable applications to representation theory, physics and to the construction of algebraic codes.
The goal of the course is to give a basic flavour of the subject as motivation for further study through the introduction of minimal background material supplemented by a vast collection of examples. This course will introduce the basic objects in algebraic geometry: affine and projective varieties, and the maps between them. The focus will be on explicit concrete examples.
We plan to cover Sections 15 and 7 from Reid's book (see Reading List below), which include :
 basics of commutative algebra,
 Hilbert Basis Theorem and the Nullstellensatz,
 affine and projective varieties,
 morphisms and rational maps between varieties,
 conics, plane curves, quadric surfaces. 
Course description 
A first course in algebraic geometry is a basic requirement for study in geometry, algebraic number theory or algebra at the MSc or PhD level.
This syllabus is for guidance purposes only :
Weeks 12. Projective plane, conics, plane curves.
Weeks 34. Cubic curves (elliptic curves). Bezout's theorem (without proof) and its applications (CayleyBacharach theorem).
Weeks 56. Affine varieties and their rings of functions. Hilbert Basis Theorem and the Nullstellensatz. Projective varieties.
Weeks 78. Quadric surfaces, blow ups, rational and birational maps.
Weeks 910. Basics of cubic surfaces. 27 lines on a smooth cubic
surface.
Week 11. Revision.
