Periodicity characterization by capacities for star-shaped domains
Jean Gutt, Vinicius G. B. Ramos, Shira Tanny
We complete the spectral characterization of Besse and Zoll Reeb flows on the standard contact sphere initiated by Ginzburg-Gürel-Mazzucchelli. Roughly speaking, it stat…

Embedded contact homology of the unit cotangent bundle of the Klein bottle
Marcelo Miranda, Vinicius G. B. Ramos
We give a combinatorial description of the embedded contact homology chain complex of the unit cotangent bundle of the Klein bottle with the standard flat Riemannian metric. Using…

The equivalence of Ekeland-Hofer and equivariant symplectic homology capacities
Jean Gutt, Vinicius G. B. Ramos
In this paper, we prove that the Ekeland-Hofer capacities coincide on all star-shaped domain in with the equivariant symplectic homology capacities defined by the…
