Cross-caps, triple points and a linking invariant for finitely determined germs

Gergő Pintér, András Sándor

It was recently proved that for finitely determined germs $\Phi :({\mathbb{C}}^2,0)\to ({\mathbb{C}}^3,0)$ the number $C(\Phi )$ of Whitney umbrella points and the number $T(\Phi )$ of tri…
