Detecting invariant manifolds of dynamical systems using persistent homology
Stavros Anastassiou, Žiga Virk
We use methods of Persistent Homology Theory to study invariant manifolds of dynamical systems. We first establish connections between the persistence diagrams of two sets which ar…
Planar vector fields in the kernel of a 1--form
Stavros Anastassiou
We classify, up to a natural equivalence relation, vector fields of the plane which belong to the kernel of a 1--form. This form can be closed, in which case the vector fields are…
Local models for smooth vector fields of the line
Stavros Anastassiou
We present the local classification of singularities of smooth vector fields on the line, with respect to the equivalence relation of --conjugacy. Along the way, we recall the…
Singularities of 3d vector fields preserving the form of Martinet
Stavros Anastassiou
We study the local structure of vector fields on which preserve the Martinet -form . We present the classification of their singularities, up t…
