Classification of rational differential forms on the Riemann sphere, via their isotropy group
Alvaro Alvarez-Parrilla, Martín Eduardo Frías-Armenta, Carlos Yee-Romero
We classify the rational differential 1-forms with simple poles and simple zeros on the Riemann sphere according to their isotropy group; when the 1-form has exactly two poles the…

On the geometry, flows and visualization of singular complex analytic vector fields on Riemann surfaces
Alvaro Alvarez-Parrilla, Jesús Muciño-Raymundo, Selene Solorza-Calderón +1
Motivated by the wild behavior of isolated essential singularities in complex analysis, we study singular complex analytic vector fields on arbitrary Riemann surfaces . By v…

Phase space deformations in phantom cosmology
J. L. Lopez, M. Sabido, C. Yee-Romero
We discuss the physical consequences of making general phase space deformations on the minisuperspace of phantom cosmology. Based on the principle of physically equivalent descript…
