Cohomological connectivity of perturbations of map-germs

Yongqiang Liu, Guillermo Peñafort Sanchis, Matthias Zach

Let $f : (C^{n}, S) \to (C^{p}, 0)$ be a finite map-germ with $n < p$ and $Y_{δ}$ the image of a small perturbation $f_{δ}$ . We show that the reduced cohomology of $Y_{δ}$ is…

On k-folding map-germs and hidden symmetries of surfaces in the Euclidean 3-space

G. Peñafort Sanchis, F. Tari

Let $M$ be a smooth surface in $R^{3}$ (or a complex surface in $C^{3}$ ) and $k \geq 2$ be an integer. At any point on $M$ and for any plane in $R^{3}$ , we constru…

Image Milnor number formulas for weighted-homogeneous map-germs

Irma Pallarés Torres, Guillermo Peñafort Sanchis

We give formulas for the image Milnor number of a weighted-homogeneous map-germ $(C^{n}, 0) \to (C^{n + 1}, 0)$ , for $n = 4$ and $5$ , in terms of weights and degrees. Our e…
