## Learning Outcomes

The students will learn the powerful machinery and language of commutative algebra and algebraic geometry. This will give them preliminary access to the vast literature on algebraic geometry, and allow to start understanding and using the tremendous progress in the field that was achieved in the 20th centuary.
