Jacobian-squared function-germs

Takashi Nishimura

In this paper, it is shown that, for any equidimensional $C^{\infty}$ map-germ $f : (R^{n}, 0) \to (R^{n}, 0)$ , the map-germ $F: (\mathbb{R}^n, 0) \to \mathbb{R}^n\times\ma…

Generic singularities of spherical orthotomic curves associated with spherical pedal curves

Xihe Liu, Takashi Nishimura

For the n-dimensional spherical pedal curve $p e d_{γ, P}$ with respect to an n-dimensional spherical unit speed curve $γ$ and a given point $P \in S^{n}$ , we define the spherical ortho…
