Some real {Rel} trajectories in that are not recurrent
Carlos Ospina
The paper investigates real Rel orbits of translation surfaces in the stratum H(1,1), providing criteria for when these orbits are recurrent and presenting explicit examples of non…
Coboundaries of 3-IETs
PrzemysÅaw Berk, Carlos Ospina
In this note, we investigate coboundaries of interval exchange transformations of three intervals, or 3-IETs. More precisely, we study differentiable functions whose derivative is…
On the diffraction spectrum of the set of visible points in lattices and certain cut-and-project sets
Rishi Kumar, Carlos Ospina
Let be a positive integer. It is known that the set of visible lattice points from the origin in has a translation bounded pure point diffraction spectrum.…
Slow entropy and variational dynamical systems
Minhua Cheng, Carlos Ospina, Kurt Vinhage +1
We define variational properties for dynamical systems with subexponential complexity, and study these properties in certain specific examples. By computing the value of slow entro…
