On accumulation points of volumes of stable surfaces with one cyclic quotient singularity
(2021)
The set of volumes of stable surfaces does have accumulation points. In this paper, we study this phenomenon for surfaces with one cyclic quotient singularity, towards answering the question under which conditions we can ...
Contact properties of surfaces in r-3 with corank 1 singularities
(Tohoku University, 2015-03-01)
We study the geometry of surfaces in R-3 with corank 1 singularities. At a singular point we define the curvature parabola using the first and second fundamental forms of the surface, which contains all the local second ...
On the index of principal foliations of surfaces in R3with corank 1 singularities
(2020-01-01)
It is well known that the index associated to the principal foliations at a cross-cap point is 1/2. In this work we study the index for other corank 1 singularities from (R2, 0) to (R3, 0) which either are simple or are ...

Sobre a geometria diferencial de certas frontais no 3-espaço Euclidiano
(Universidade Estadual Paulista (Unesp), 2022-08-31)
Este trabalho busca estudar a geometria diferencial de algumas classes de superfícies com singularidades que não são necessariamente não degeneradas ou frentes. Dentre elas, estudamos a superfície singular D4, que é uma ...

Integrable Systems and projective images of Kummer surfaces
(Scuola Normale Superiore, 2000-10)
The (-1 )-involution on the Jacobian Jr of an arbitrary Riemann surfacer of genus two leads to a singular surface, the Kummer surface Icr of Jr, which,after desingularization, defines a X-3 surface Kr . We consider ample ...
