Closed Orbits of Dynamically Convex Reeb Flows: Towards the HZ- and Multiplicity Conjectures

Erman Cineli, Viktor L. Ginzburg, Basak Z. Gurel

We study the multiplicity problem for prime closed orbits of dynamically convex Reeb flows on the boundary of a star-shaped domain in . The first of our two main r…

Filtered Symplectic Homology and Closed Reeb Orbits

Erman Cineli, Viktor L. Ginzburg, Basak Z. Gurel

We further explore connections between the symplectic homology persistence module and the properties of closed Reeb orbits for star-shaped domains in higher dimensions. Our first r…

From Barcode Entropy to Metric Entropy

Erman Cineli, Viktor L. Ginzburg, Basak Z. Gurel

We establish a connection between barcode entropy and metric entropy. Namely, we show that the barcode entropy bounds the metric entropy from below for a measure from a specific cl…

Topics in Symplectic Dynamics: Barcode Entropy

Erman Cineli, Viktor L. Ginzburg, Basak Z. Gurel +1

Barcode entropy is an invariant of a Hamiltonian system -- a Hamiltonian diffeomorphism or a Reeb flow -- measuring its Morse or Floer theoretic complexity at a small scale. More s…

On the Barcode Entropy of Reeb Flows

Erman Cineli, Viktor L. Ginzburg, Basak Z. Gurel +1

In this paper we continue investigating connections between Floer theory and dynamics of Hamiltonian systems, focusing on the barcode entropy of Reeb flows. Barcode entropy is the…

Invariant Sets and Hyperbolic Closed Reeb Orbits

Erman Cineli, Viktor L. Ginzburg, Basak Z. Gurel +1

We investigate the effect of a hyperbolic (or, more generally, isolated as an invariant set) closed Reeb orbit on the dynamics of a Reeb flow on the -dimensional standard c…
