Abstract

The idea of the project is to acquaint the student with the concept of index of vector fields and 1-forms defined on singular varieties, seeking to understand the different generalizations of the concept for such objects, based on the of the Poincaré-Hopf Index for vector fields on smooth manifolds. The main goal of the project is the investigation of different versions of the Poincaré-Hopf Theorem for vector fields and 1-forms on singular varieties, allowing a comparison between the generalizations of the concept of index and the classical Poincaré-Hopf Index.
