The flat geometry of the $I_{1}$ singularity: $(x, y) \mapsto (x, x y, y^{2}, y^{3})$

Pedro Benedini Riul, Raúl Oset Sinha

We study the flat geometry of the least degenerate singularity of a singular surface in $R^{4}$ , the $I_{1}$ singularity parametrised by $(x, y) \mapsto (x, x y, y^{2}, y^{3})$ . Thi…

The geometry of corank $1$ surfaces in $R^{4}$

Pedro Benedini Riul, Raúl Oset Sinha, Maria Aparecida Soares Ruas

We study the geometry of surfaces in $R^{4}$ with corank $1$ singularities. For such surfaces the singularities are isolated and at each point we define the curvature para…
