The local Euler obstruction and topology of the stabilization of associated determinantal varieties
Terence Gaffney, Nivaldo G. Grulha, Maria A. S. Ruas
This work has two complementary parts, in the first part we compute the local Euler obstruction of generic determinantal varieties and apply this result to compute the Chern--Schwa…
Whitney equisingularity of families of surfaces in
M. A. S. Ruas, O. N. Silva
In this work, we study families of singular surfaces in parametrized by -finitely determined map germs. We consider the topological triviality and Whitn…
Lipschitz Normal Embeddings and Determinantal Singularities
Helge Møller Pedersen, Maria Aparecida Soares Ruas
The germ of an algebraic variety is naturally equipped with two different metrics up to bilipschitz equivalence. The inner metric and the outer metric. One calls a germ of a variet…
On the Zariski multiplicity conjecture for weighted homogeneous and Newton non-degenerate line singularities
Christophe Eyral, Maria Aparecida Soares Ruas
We present new families of weighted homogeneous and Newton non-degenerate line singularities that satisfy the Zariski multiplicity conjecture.
Equisingularity and EIDS
Terence Gaffney, Maria Aparecida Ruas
The study of Essentially Isolated Determinantal Singularites or EIDS was initiated by Ebeling and Gusein-Zade. They are non-smoothable as determinantal singularities, and in genera…
