Singular 3-manifolds in $R^{5}$

Pedro Benedini Riul, Maria Aparecida Soares Ruas, Andrea de Jesus Sacramento

We study 3-manifolds in $R^{5}$ with corank $1$ singularities. At the singular point we define the curvature locus using the first and second fundamental forms, which contai…

Finite $A$ -determinacy of generic homogeneous map germs in $C^{3}$

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

Denote by $H (d_{1}, d_{2}, d_{3})$ the set of all homogeneous polynomial mappings $F=(f_1,f_2,f_3): \C^3\to\C^3$, such that $° f_{i} = d_{i}$ . We show that if $g cd (d_{i}, d_{j}) \leq 2$ for $1\leq i<j…

Local bi-Lipschitz classification of semialgebraic surfaces

Jean-paul Brasselet, Maria Aparecida Soares Ruas, Thuy Nguyen

We provide bi-Lipschitz invariants for finitely determined map germs $f : (K^{n}, 0) \to (K^{p}, 0)$ , where $K = R$ or $C$ . The aim of the p…
