Learning objectives
Introduction to complex geometry. Cohomological aspects of complex manifolds.
At the end of the course, students will be familiar with the theory of holomorphic function of several complex variables, with the differential calculus on complex maniflds and with the Hodge theory on compact Hermitian manifolds. They will also be able to tackle the resolution of problems of a theoretical and practical nature in the area of complex differential geometry.

Teaching methods
Lectures and classroom exercises.
During lectures in traditional mode, the
topics will be formally and rigorously presented. The course will give particular emphasis to application and computation aspects, while not letting out
the theoretical aspect. The classroom exercises are aimed at showing how and where the abstract results can be applied to make the students understand better the relevance of what they are studying.
Assessment methods and criteria
The final exam consists of an oral test and the resolution of exercises assigned during the course on the elly platform.
Other information
Exercises and problems to be performed outside of class hours will be assigned by the teacher.
Notes from the teacher will be distributed. The course notes in PDF format and all the material used during the lessons and exercises are made available to the students on the Elly educational platform.
