Abstract
This project proposes the study of invariants related to germs of analytical varieties and their relationship with equisingularities of families of such germs. More specifically, let's consider $\Sigma$-singularities: defined as inverse images by applications of a variety $\Sigma$ in the target with the expected codimension and defines invariants such as the evanescent Euler characteristic and the polar multiplicities of such varieties to later study equisingularities in families. Also, let's consider holomorphic map germs $f:(X,0)\to(\C^p,0)$ to see the relationship between the invariants that can be related to such germs and what they can tell us about equisingularity. Furthermore, we intend to continue our work on injectivity of polynomial maps $f:\R^2\to\R^2$. (AU)
