Star vector fields on three-manifolds are multi-singular hyperbolic
Jennyffer Bohorquez, Adriana da Luz, Nelda Jaque
The coexistence of singularities and regular orbits in chain transitive sets has been a major obstacle in understanding the hyperbolic/partial hyperbolic nature of robust dynamics.…

On two notions of expansiveness for continuous semiflows
Sebastián Herrero, Nelda Jaque
We study two notions of expansiveness for continuous semiflows: expansiveness in the sense of Alves, Carvalho and Siqueira (2017), and an adaptation of positive expansiveness in th…

Topological entropy and metric entropy for regular impulsive semiflows
Nelda Jaque, Bernardo San Martín
In arXiv:1801.01238 a variation of Bowen's topological entropy that can be applied to the study of discontinuous semiflows on compact metric spaces was introduced. The main novetly…
