On the Tame Isotropy Group of Locally Finite Derivations of K[X,Y]
Luis Cid, Marcelo Veloso
Let K be an algebraically closed field of characteristic zero. We study the tame isotropy group Tame_D(K[X,Y]) of locally finite derivations of the polynomial ring K[X,Y], using Va…
On isotropy group of locally finite derivations on
Luis Cid, Marcelo Veloso
In this paper, we study the isotropy groups of locally finite derivations of the polynomial ring , using Van den Essen's classification of locally finite derivatio…
On the tame isotropy group of a derivation
Angelo Bianchi, Adriana Freitas, Marcelo Veloso
We introduce the tame isotropy group of a derivation of a polynomial ring. We study this group for certain triangular derivations up to three variables, for simple derivations in t…
On -primitive points on hypersurfaces
José Alves Oliveira, Marcelo Oliveira Veloso
In this paper, we estimate the number of -primitive points on the affine hypersurface defined by the equation , where $f\in\mathbb{F}_q[x_1,\dots…
