Computing a Saito basis from a standard basis

Felipe Cano, Nuria Corral, David Senovilla-Sanz

In this paper we describe how to compute a Saito basis of a cusp, a plane curve with only one Puiseux pair. Moreover, the 1-forms of the Saito basis that we compute are characteriz…

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…

Intrinsic potentials in locally harmonic manifolds

Carlos Beltrán, Nuria Corral, Juan G. Criado del Rey

We consider the problem of allocating a finite number of heat sources in the n-dimensional sphere. When only one such source -assumed to be of infinite temperature- is placed and a…
