Line Congruences on singular surfaces

Débora Lopes, Tito Alexandro Medina Tejeda, Maria Aparecida Soares Ruas +1

This paper is a first step in order to extend Kummer's theory for line congruences to the case ${x, ξ}$ , where $x : U \to R^{3}$ is a smooth map and $ξ:…

Equiaffine structure on frontals

Igor Chagas Santos

In this paper, we generalize the idea of equiaffine structure to the case of frontals and we define the Blaschke vector field of a frontal. We also investigate some necessary and s…
