K-stability of Casagrande-Druel varieties
Ivan Cheltsov, Tiago Duarte Guerreiro, Kento Fujita +2
We introduce a new subclass of Fano varieties (Casagrande-Druel varieties), that are -dimensional varieties constructed from Fano double covers of dimension . We conjecture…
One-dimensional components in the K-moduli of smooth Fano 3-folds
Hamid Abban, Ivan Cheltsov, Elena Denisova +5
By identifying K-polystable limits in 4 specific deformations families of smooth Fano 3-folds, we complete the classification of one-dimensional components in the K-moduli space of…
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…
On maximally non-factorial nodal Fano threefolds
Ivan Cheltsov, Igor Krylov, Jesus Martinez-Garcia +1
We classify non-factorial nodal Fano threefolds with node and class group of rank .
