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…

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

Thaís 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…

Modules of derivations, logarithmic ideals and singularities of maps on analytic varieties

Carles Bivià-Ausina, Konstantinos Kourliouros, Maria Aparecida Soares Ruas

We introduce the module of derivations attached to a given analytic map and a submodule and analyse sev…

Bruce-Roberts Numbers and Quasihomogeneous Functions on Analytic Varieties

Carles Bivià-Ausina, Konstantinos Kourliouros, Maria Aparecida Soares Ruas

Given a germ of an analytic variety and a germ of a holomorphic function with a stratified isolated singularity with respect to the logarithmic stratification of , we sh…
