Axial curvatures for corank 1 singular -manifolds in
Pedro Benedini Riul, Jorge Luiz Deolindo Silva, Raúl Oset Sinha
For singular -manifolds in with a corank 1 singular point at $p\in M^n_{\mbox{sing}}$ we define up to different axial curvatures at , where $l=\min…
Cr-invariants for surfaces in 4-space
Jorge Luiz Deolindo Silva
We establish cross-ratio invariants for surfaces in 4-space in an analogous way to Uribe-Vargas's work for surfaces in 3-space. We study the geometric locii of local and multi-loca…
Binary differential equations at parabolic and umbilical points for -parameter families of surfaces
Jorge Luiz Deolindo Silva, Yutaro Kabata, Toru Ohmoto
We determine local topological types of binary differential equations of asymptotic curves at parabolic and flat umbilical points for generic -parameter families of surfaces in…
Projective classification of jets of surfaces in
Jorge Luiz Deolindo Silva, Yutaro Kabata
We are interested in the local extrinsic geometry of smooth surfaces in 4-space, and classify jets of Monge forms by projective transformations according to -types o…
Projective classification of jets of surfaces in 3-space
Hiroaki Sano, Yutaro Kabata, Jorge Luiz Deolindo Silva +1
We present a local classification of smooth projective surfaces in 3-space via projective transformations in accordance with singularity types of central projections up to codimens…
