Commutative Algebra

A.Y. 2019/2020
Overall hours
Learning objectives
The main task is to give an introduction to modern commutative algebra with a special regard to commutative ring theory, arithmetic, homological methods and algebraic geometry.
Expected learning outcomes
(first part) Theory and computations of primary decompositions, integral extensions, regular rings & a first step in dimension theory. (9 credits) The additional 3 credits course is providing the next key step in dimension theory.
Course syllabus and organization

Single session

Lesson period
First semester
Prerequisites for admission
We assume known the basic language of categories and functors up to the Yoneda Lemma. We also assume the standard notions: ideals, polynomial rings, multiplicatively closed subsets and localizations, tensor products of modules, Noetherian rings & modules. For example, with respect to M. Reid Undergraduate Commutative Algebra LMS student text series C.U.P. 1995 we will be dealing fast with Chapters 4, 5 & 7, 8 in the commutative algebra course assuming the other Chapters.
Assessment methods and Criteria
The final examination consists of three parts: a written exam, an oral exam and some homework.
