Aim: The course intends to give a first introduction to the basic notions and techniques of algebraic geometry

Description: This introduction begins with varieties defined over an algebraically closed field. We treat basic notions like dimension, tangent space and smoothness. We continue with divisors, line bundles and differential forms. We shall treat a number of basic results on algebraic curves. We also intend to give a first encounter with schemes.

Organization: There will be three hours of lectures every week. Exercises will be given so that students can test their progress.

Examination: There will a written final exam. During the course there will be a few diagnostic tests that do not count for the final grade.

Literature: We shall use the course notes of Ben Moonen as the basic text. In the last two lectures we also use the addendum by Robin de Jong. Besides that we shall refer the students to Hartshorne's book 'Algebraic Geometry' and the book 'Geometry of Schemes' by Eisenbud and Harris. For those who want to pursue in algebraic geometry it may be recommended to buy these books, esp. the book by Hartshorne
