| Fecha: | 2025 |
| Resumen: | Consider a planar autonomous differential equation with a unique degenerated singularity inside a flow box with two transversal sections in such a way that a Poincar'e map between them is well defined by the flow. We are interested in understanding what effect this singularity has on the properties of the Poincar'e map between the transversal sections. The fiber containing the singularity is usually called singular fiber and, in particular, we want to determine its attractive or repulsive character. We prove that there is a real value whose sign determines the stability of the singular fiber. This value is given by the principal value of a suitable integral constructed from the corresponding differential equation. |
