Behavior of corank one singular points on wave fronts

Kentaro Saji, Masaaki Umehara, Kotaro Yamada

Let $M^{2}$ be an oriented 2-manifold and $f : M^{2} \to R^{3}$ a $C^{\infty}$ -map. A point $p \in M^{2}$ is called a singular point if $f$ is not an immersion at $p$ . The map $f$ is called a fr…

The geometry of fronts

Kentaro Saji, Masaaki Umehara, Kotaro Yamada

We shall introduce the singular curvature function on cuspidal edges of surfaces, which is related to the Gauss-Bonnet formula and which characterizes the shape of cuspidal edges.…
