Commutative Algebra and Algebraic Geometry
Algebraic geometry is the study of systems of polynomial equations and their geometric counterparts, namely, algebraic varieties. Commutative algebra is the subfield of algebra that deals with commutative rings and their modules; it provides the tools to effectively analyse algebraic varieties.
In this introductory course, we will consider a special family of algebraic varieties, namely, projective ones: they are the zero sets of homogenous polynomials in an extension of the standard affine space, which is called the projective space. The algebraic couterpart to projective varieties are homogeneous ideals and graded modules. We will study the basic properties of these objects and of the maps between them.
The exercise course is taught by Professor Josef Schicho. You can find information about his course at this link.
Language: the course will be taught in English.
Time: Tuesdays, 8:30-10:00 (for precise dates, please check on KUSSS)
Place: room S2 054 in Science Park 2
