Strongly incompressible curves

Mario Garcia-Armas

Let $G$ be a finite group. A faithful $G$ -variety $X$ is called strongly incompressible if every dominant $G$ -equivariant rational map of $X$ onto another faithful $G$ -variety $Y$ …

Finite group actions on curves of genus zero

Mario Garcia-Armas

We classify, up to conjugacy, the finite (constant) subgroups G of adjoint absolutely simple algebraic groups of type $A_{1}$ over an arbitrary field $k$ of characteristic not 2.

Relatively Prime Polynomials and Nonsingular Hankel Matrices over Finite Fields

Mario Garcia Armas, Sudhir R. Ghorpade, Samrith Ram

The probability for two monic polynomials of a positive degree n with coefficients in the finite field F_q to be relatively prime turns out to be identical with the probability for…

A common formula for certain generalized Hankel transforms

Mario Garcia-Armas

We study the generalized Hankel transform of the family of sequences satisfying the recurrence relation $a_{n + 1} = (α + \frac{β}{n + γ}) a_{n}$ . We apply the obtained formula to…
