Abstract

The PhD project is about the Geometry of singular surfaces in R3, using Singularity Theory tools. This project intends to investigate local properties of singular surfaces, such as those of rotation obtained from singular generative curves, as well as those that are focal surfaces of singular surfaces of rotation, hoping to obtain geometric properties, invariants and relations between geometrical properties of the focal surface and of the initial surface of rotation. It is also intended to explore other singular surfaces, such as generalized helicoids, among others that may arise during the study. The project also contemplates theinvariants associated with singularities andof formulas related to them. Through a scholarship application for research abroad (BEPE), we intend to maintain a partnership with K. Saji and K. Teramoto, from the University of Kobe, Japan, who are authors of the main scientific articles that are reference for this project. (AU)
