Global smoothing of singular Fano and Calabi-Yau varieties
Anda Tenie
We study the problem of smoothing Fano and Calabi-Yau varieties with isolated Du Bois lci singularities. For Fano varieties, we show that any such admits a deformation to a Fan…
The integral chow ring of
Joseph Helfer, Eric Jovinelly, Eric Larson +2
This paper computes the integral Chow ring of the moduli space of stable genus 2 curves of compact type. This is done by excising boundary strata from one-by-…
Reider-type theorems on normal surfaces via Bridgeland stability
Anne Larsen, Anda Tenie
Using Langer's construction of Bridgeland stability conditions on normal surfaces, we prove Reider-type theorems generalizing the work done by Arcara-Bertram in the smooth case. Ou…
Strongly isospectral hyperbolic 3-manifolds with nonisomorphic rational cohomology rings
Anda Tenie
This paper shows that one cannot "hear" the rational cohomology ring of a hyperbolic 3-manifold. More precisely, while it is well-known that strongly isospectral manifolds have the…
Graph coverings and (im)primitive homology: some new examples of exceptionally low degree
Destine Lee, Iris Rosenblum-Sellers, Jakwanul Safin +1
Given a finite covering of graphs , it is not always the case that is spanned by lifts of primitive elements of . In this paper, we study g…
