Module summaryAlgebraic geometry is the study of the solution sets of polynomial equations, just as linear algebra is the study of the solution sets of linear equations. Polynomial equations in several variables are fundamental in both pure and applied mathematics since they allow us to describe many shapes, such as circles, ellipses and parabolas. Examples include the trajectory of an object moving under gravity and the points that can be reached by a robot arm.Sets of solutions of polynomial equations, known as affine varieties, have beautiful properties. The role of polynomials in their description means that they can be studied via commutative rings, such as polynomial rings. There is thus a rich interplay between the geometry of varieties and the algebraic properties of commutative rings. The module will introduce the basic ideas of algebraic geometry via commutative rings, with an emphasis on concrete examples and explicit calculations.
ObjectivesTo give an introduction to the theory of algebraic geometry via affine algebraic varieties.
To give an introduction to the theory and properties of the commutative rings which arise in the description of algebraic varieties.
To illustrate how commutative rings can be used to study algebraic varieties, and how the properties of each are interrelated.
In particular, to study the primary decomposition of ideals and the irreducible components of varieties and how these are related.
To focus on the use of interesting examples to illustrate ideas in the theory.
To develop the skills of rigorous logical argument and problem-solving in the context of commutative rings, algebraic geometry and their interaction.
On completion of this module, students should be able to:
(a) Define and use key concepts in commutative rings and algebraic geometry;
(b) State and prove basic results in commutative rings and algebraic geometry;
(c) Solve simple problems concerning varieties;
(d) Understand the relationship between ideals and varieties.
