Romero Fuster, M. C. Stereographic projections and geometric singularities. (English) Zbl 0939.58036 Mat. Contemp. 12, 167-182 (1997). Author’s abstract: “We relate the contacts of \(k\)-spheres and submanifolds of \(\mathbb{R}^n\) with those of \((k+1)\)-planes and their inverse images through the stereographic projection in \(\mathbb{R}^{n+1}\) by defining \({\mathcal K}\)-equivalences between their respective families of contact maps”.
