Educational objectives | The course introduces to the theory of algebraic varieties as ringed spaces. Its goal is to familiarize the students with the tools they will need in order to use algebraic varieties, also with regard to other fields of the geometry. |
Prerequisites | Elements of commutative algebra and fields theory, wich are stated as needed, and some elementary topology. |
Teaching methods | face-to-face, office hours, usage of the platform “Unistudium” (https://www.unistudium.unipg.it) |

Learning verification modality | The final exam consists in an oral discussion of about an hour on the subjects developped during the course. A detailed list of the subjects is provided at the end of the lectures. The aim of the exam is to evaluate the level and the quality of the knowledge the students have acquired and to check their ability in the exposition. |
