The axial curvature for corank 1 singular surfaces
Raúl Oset Sinha, Kentaro Saji
For singular corank 1 surfaces in we introduce a distinguished normal vector called the axial vector. Using this vector and the curvature parabola we define a new typ…

Relating second order geometry of manifolds through projections and normal sections
Pedro Benedini Riul, Raúl Oset Sinha
We use normal sections to relate the curvature locus of regular (resp. singular corank 1) 3-manifolds in (resp. ) with regular (resp. singular corank 1)…
