The course aims to provide students with the basic concepts on Differential Geometry of manifolds.
At the end of the course the student will know the main terminology and definitions about manifolds and Riemannian manifolds, and some of the main results.
He/she will be able to produce rigorous arguments and proofs on these topics and he/she will be able to read articles and texts of Differential Geometry.
The course consists of lectures. Notes for each lecture will be provided.

During the exam, students must show that:
- they know and understand the fundamental concepts of differential geometry
- they have analytical and abstraction abilities
- they support their argumentation with mathematical rigor.
The exam consists of a written test in which the student will have to choose one of two themes in which they provide a broad discussion of one of the topics presented during the lectures (answer approximately 2/3 pages ) and two of three short questions (answer approximately 10 rows).
