Ga-actions of fiber type on affine T-varieties

Alvaro Liendo

Let X be a normal affine T-variety, where T stands for the algebraic torus. We classify Ga-actions on X arising from homogeneous locally nilpotent derivations of fiber type. We ded…

Rational singularities of normal T-varieties

Alvaro Liendo

A T-variety is an algebraic variety X with an effective regular action of an algebraic torus T. Altmann and Hausen gave a combinatorial description of an affine T-variety X by mean…
