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 $X$ and a germ of a holomorphic function $f$ with a stratified isolated singularity with respect to the logarithmic stratification of $X$ , we sh…

The extra-nice dimensions

Raúl Oset Sinha, Maria Aparecida Soares Ruas, Roberta Wik Atique

We define the extra-nice dimensions and prove that the subset of locally stable 1-parameter families in $C^{\infty} (N \times [0, 1], P)$ , also known as pseudo-isotopies, is dense if an…

Topological Triviality of Families of Singular Surfaces

R. Callejas-Bedregal, K. Houston, M. A. S. Ruas

We study the topological triviality of families of singular surfaces in $C^{3}$ parametrized by $A$ -finitely determined map germs. We prove that the constancy of t…
