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…

Finite -determinacy of generic homogeneous map germs in

M. Farnik, Z. Jelonek, M. A. S. Ruas

Denote by the set of all homogeneous polynomial mappings $F=(f_1,f_2,f_3): \C^3\to\C^3$, such that . We show that if for $1\leq i<j…

Mixed Bruce-Roberts numbers

Carles Bivià-Ausina, María Aparecida Soares Ruas

We extend the notion of -sequence and Tjurina number of functions to the framework of Bruce-Roberts numbers, that is, to pairs formed by the germ at of a complex analytic…

Classification of Lipschitz simple function germs

Nhan Nguyen, Maria Ruas, Saurabh Trivedi

It is known that the bi-Lipschitz right classification of function germs admit moduli. In this article we introduce a notion called the Lipschitz simple function germs and present…
