Exams after the reopening

As a general rule, exams will be conducted without physical attendance in the autumn of 2021, even after the reopening. See the semester page for information about the form of examination in your course. See also more information about examination at the MN Faculty in 2021.

Course content

Algebraic geometry is a classical subject with a modern face that studies geometric objects defined by polynomial equations in several variables. The course introduces the basic objects in algebraic geometry: Affine and projective varieties and maps between them. It covers the concepts of dimension, singularities, curves and intersection theory form a geometric and an algebraic point of view. There is a particular emphasis on concrete examples. Introduction to algebraic curves and varieties.

Learning outcome

After completing the course you:

  • know the definitions and basic properties of algebraic varieties;
  • know the relation between dimension in commutative rings and in algebraic sets;
  • can perform computations with morphisms and rational maps between algebraic varieties;
  • can decide whether an algebraic variety is singular;
  • can use blowing up to resolve plane curve singularities;
  • know the properties of the Hilbert polynomial and can compute it for selected projective varieties;
  • know the Bezout theorem and can use it in geometric applications;
  • are familiar with applications of algebraic methods in geometry.
