On the simplicity of multigerms
Raúl Oset Sinha, Maria Aparecida Soares Ruas, Roberta Wik Atique
We prove several results regarding the simplicity of germs and multigerms obtained via the operations of augmentation, simultaneous augmentation and concatenation and generalised c…
Singularities of affine equidistants: extrinsic geometry of surfaces in 4-space
W. Domitrz, S. Janeczko, P. de M. Rios +1
For a generic embedding of a smooth closed surface into , the subset of which is the affine -equidistant of appears as the discriminant set of…
Generic sections of essentially isolated determinantal singularities
Jean-Paul Brasselet, Nancy Chachapoyas, Maria A. S. Ruas
We study the essentially isolated determinantal singularities (EIDS), defined by W. Ebeling and S. Gusein-Zade, as a generalization of isolated singularity. We prove in dimension $…
On a singular variety associated to a polynomial mapping from $\C^n$ to $\C^{n-1}$
Nguyen Thi Bich Thuy, Maria Aparecida Soares Ruas
We construct a singular variety associated to a polynomial mapping $G : \C^{n} \to \C^{n - 1}$ where . We prove that in the case $G : \C^{3} \to \C^{2}$…
Effective Whitney theorem for complex polynomial mappings of the plane
M. Farnik, Z. Jelonek, M. A. S. Ruas
We describe the topology of a general polynomial mapping
