Computation of GIT quotients of semisimple groups
Patricio Gallardo, Jesus Martinez-Garcia, Han-Bom Moon +1
We describe three algorithms to determine the stable, semistable, and torus-polystable loci of the GIT quotient of a projective variety by a reductive group. The algorithms are eff…

Higher-dimensional Losev-Manin spaces and their geometry
Patricio Gallardo, Javier González-Anaya, José Luis González +1
The classical Losev-Manin space is a toric compactification of the moduli space of points in the affine line modulo translation and scaling. Motivated by this, we study its hig…
