The equations of general Hassett maximal cubic fourfolds

Elad Gal, Howard Nuer

In this note, we discuss Hassett maximal cubic fourfolds and construct an explicit irreducible component of maximal dimension sixteen of the locus of Hassett maximal…

Finite order symplectic birational self-maps on Kummer-type manifolds

Yajnaseni Dutta, Dominique Mattei, Stevell Muller +1

A projective hyperkähler manifold of Kummer-type is said to be twisted modular if it is birational to the Albanese fiber of a moduli space of twisted sheaves on an abelian surface.…

Stability conditions on some families of Calabi-Yau threefolds via orbifolding

Howard Nuer

We prove that families of Calabi-Yau threefolds (CY3's) admit Bridgeland stability conditions when they are obtained via orbifolding from a family of CY3's admitting Bridgeland sta…

Weak Brill-Noether on Abelian Surfaces

Izzet Coskun, Howard Nuer, Kota Yoshioka

We study the cohomology of a general stable sheaf on an abelian surface. We say that a moduli space satisfies weak Brill-Noether if the general sheaf has at most one non-zero cohom…

Supporting rank and the intersection of all Hassett Divisors

Elad Gal, Howard Nuer

We prove that the dimension of the intersection of all Hassett divisors of special cubic fourfolds is sixteen. We do this by studying which subsets of the natural numb…

The Bogomolov-Gieseker-Koseki inequality on surfaces with canonical singularities in arbitrary characteristic

Howard Nuer, Alan Sorani

This note generalizes the celebrated Bogomolov-Gieseker inequality for smooth projective surfaces over an algebraically closed field of characteristic zero to projective surfaces i…

The Brill-Noether Theory of the Moduli Spaces of Sheaves on Surfaces

Izzet Coskun, Jack Huizenga, Howard Nuer

In this paper, we survey recent developments in the Brill-Noether Theory of higher rank vector bundles on complex projective surfaces. We focus on weak Brill-Noether Theorems on ra…

Stable sheaves on bielliptic surfaces: from the classical to the modern

Howard Nuer

Bielliptic surfaces are the last family of Kodaira dimension zero algebraic surfaces without a classification result for the Chern characters of stable sheaves. We rectify this and…

A Refined Derived Torelli Theorem for Enriques surfaces, II: the non-generic case

Chunyi Li, Paolo Stellari, Xiaolei Zhao

We prove that two Enriques surfaces defined over an algebraically closed field of characteristic different from are isomorphic if their Kuznetsov components are equivalent. Thi…

Stability conditions in families

Arend Bayer, Martí Lahoz, Emanuele Macrì +3

We develop a theory of Bridgeland stability conditions and moduli spaces of semistable objects for a family of varieties. Our approach is based on and generalizes previous work by…

MMP Via Wall-crossing for Moduli Spaces of Stable Sheaves on an Enriques surface

Howard Nuer, Kōta Yoshioka

We use wall-crossing in the Bridgeland stability manifold to systematically study the birational geometry of the moduli space of -semistable objects of class $…

Ulrich Bundles on Enriques Surfaces

Lev Borisov, Howard Nuer

We study Ulrich bundles and their moduli on unnodal Enriques surfaces. In particular, we prove that unnodal Enriques surfaces are of wild representation type by constructing moduli…

Unirationality of moduli spaces of special cubic fourfolds and K3 surfaces

Howard Nuer

We provide explicit descriptions of the generic members of Hassett's divisors for relevant and for . In doing so, we prove that $\mathcal C_d…

Projectivity and Birational Geometry of Bridgeland Moduli spaces on an Enriques Surface

Howard Nuer

We construct moduli spaces of semistable objects on an Enriques surface for generic Bridgeland stability condition and prove their projectivity. We further generalize classical res…

A Strange Family of Calabi-Yau 3-folds

Patrick Devlin, Howard J. Nuer

We study the predictions of mirror symmetry for the 1-parameter family of Calabi-Yau 3-folds with hodge numbers constructed in \cite{BN}. We calcul…

On complete intersection threefolds that contain an Enriques surface

Lev A. Borisov, Howard J. Nuer

We study nodal complete intersection threefolds of type in $\PP^5$ which contain an Enriques surface in its Fano embedding. We completely determine Calabi-Yau birational mo…
