Two remarks on asymptotically log Fano pairs
Jesus Martinez-Garcia
Asymptotically log Fano pairs were introduced by Cheltsov and Rubinstein, generalising a definition of Maeda. They have received attention in the last decade within the theory of K…
The CompGIT package: a computational tool for Geometric Invariant Theory quotients
Robert Hanson, Jesus Martinez-Garcia
We describe CompGIT, a SageMath package to describe Geometric Invariant Theory (GIT) quotients of projective space by simple groups. The implementation is based on algorithms descr…
K-moduli of log del Pezzo pairs and variations of GIT
Jesus Martinez-Garcia, Theodoros Stylianos Papazachariou, Junyan Zhao
We study the K-moduli of log del Pezzo pairs formed by a del Pezzo surface of degree and an anti-canonical divisor. These moduli spaces naturally depend on one parameter, provi…
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 .
