On the topology of complex map-germs and a general Lê-Greuel formula

Lê Dũng Tráng, Juan J. Nuño-Ballesteros, José Seade

Consider a singular holomorphic map-germ $f : (X, 0) \to (C, 0)$ where $X$ is a singular complex analytic variety in $C^{N}$ , and another holomorphic map-ger…

Counting $D_{4}$ singularities in the image of a wave front

C. Muñoz-Cabello, J. J. Nuño-Ballesteros, R. Oset Sinha

We give a formula to count the number of $D_{4}$ singularities in a stable frontal perturbation of a corank $2$ wave front singularity $f : (C^{3}, 0) \to (C^{4}, 0)$ …
