Toric varieties with isolated singularity and smooth normalization
Thais Maria Dalbelo, Maria Elenice Rodrigues Hernandes, Maria Aparecida Soares Ruas
In this work, we describe a prenormal form for the generators of the semigroup of a toric variety with isolated singularity at the origin and smooth normal…

Nash blowups of 2-generic determinantal varieties in positive characteristic
ThaÃs M. Dalbelo, Daniel Duarte, Maria Aparecida Soares Ruas
We show that the Nash blowup of 2-generic determinantal varieties over fields of positive characteristic is non-singular. We prove this in two steps. Firstly, we explicitly describ…

Bi-Lipschitz triviality of function-germs on singular varieties
Raúl Oset Sinha, Maria Aparecida Soares Ruas
In this paper we study the bi-Lipschitz triviality of deformations of an analytic function germ defined on a germ of an analytic variety in . We introduce…
