New paper out in Med. Journal of Mathematics
A. Gasull & D. Rojas study when the period of periodic orbits changes monotonically in equivariant differential equations with homogeneous nonlinearities. Symmetry + dynamics in action.
DOI: doi.org/10.1007/s000...

Monotonous Period Function for Equivariant Differential Equations with Homogeneous Nonlinearities - Mediterranean Journal of Mathematics
We prove that the period function of the center at the origin of the $$\mathbb {Z}_k$$ Z k -equivariant differential equation $$\dot{z}=iz+a(z\overline{z})^nz^{k+1}, a\ne 0,$$ z ˙ = i z + a ( z z ¯ ) ...

New paper out in Physica D
R. Ortega & D. Rojas analyse how relativistic effects change the dynamics of a particle in a Coulomb field in a new article in Physica D. Neat bridge between mathematical physics & dynamical systems.

Our new paper finds the tree cycle with minimum positive entropy for each period. It’s the “slowest” chaotic tree map, a #Combinatorics & #Dynamics mix. Learn more: Characterization of the tree cycles with minimum positive entropy for any period, pp. 1 - 44
