Mirror Symmetry for Nonabelian Landau-Ginzburg Models
Nathan Priddis, Joseph Ward, Matthew M. Williams
We consider Landau-Ginzburg models stemming from groups comprised of non-diagonal symmetries, and we describe a rule for the mirror LG model. In particular, we present the non-abel…
-signature under birational morphisms
Linquan Ma, Thomas Polstra, Karl Schwede +1
We study -signature under proper birational morphisms , showing that -signature strictly increases for small morphisms or if . In certain cases,…
Vanishing and injectivity for R-Hodge modules and R-divisors
Lei Wu
We prove the injectivity and vanishing theorem for R-Hodge modules and R-divisors over projective varieties, extending the results for rational Hodge modules and integral divisors…
Divisor package for Macaulay2
Karl Schwede, Zhaoning Yang
This note describes a Macaulay2 package for handling divisors. Group operations for divisors are included. There are methods for converting divisors to reflexive or invertible shea…
Higher Codimensional Alpha Invariants and Characterization of Projective Spaces
Ziwen Zhu
We generalize the definition of alpha invariant to arbitrary codimension. We also give a lower bound of these alpha invariants for K-semistable Q-Fano varieties and show that we ca…
On the Kodaira problem for uniruled Kähler spaces
Patrick Graf, Martin Schwald
We discuss the Kodaira problem for uniruled Kähler spaces. Building on a construction due to Voisin, we give an example of a uniruled Kähler space such that every run of the $K…
