Surfaces with central configuration and Dulac's problem for a three dimensional isolated Hopf singularity

Nuria Corral, María Martín Vega, Fernando Sanz Sánchez

Let $ξ$ be a real analytic vector field with an elementary isolated singularity at $0 \in R^{3}$ and eigenvalues $\pm bi, c$ with $b, c \in R$ and $b \neq = 0$ . We prove t…

Stratification of three-dimensional real flows I: Fitting Domains

Clementa Alonso-González, Fernando Sanz Sánchez

Let $ξ$ be an analytic vector field in $R^{3}$ with an isolated singularity at the origin and having only hyperbolic singular points after a reduction of singularities $π:M\…
