Geodesibility of algebrizable three-dimensional vector fields
M. E. Frías-Armenta, E. López-González
Recently, the geodesibility of planar vector fields, which are algebrizable (differentiable in the sense of Lorch for some associative and commutative unital algebra), has been est…
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…
Collapsibility and homological properties of -contractible transformations
Jesus F. Espinoza, Martín-Eduardo Frías-Armenta, Héctor A. Hernández
The family of -contractible graphs and contractible transformations was defined by A. Ivashchenko in the mid-90's. In this paper we study the collapsibility and homol…
