The Lebrun--Salamon conjecture is true in dimension up to 56
Jordi Daura Serrano, Aron Gohr, Marie-Amélie Lawn +1
We prove the LeBrun--Salamon conjecture for positive quaternionic Kähler manifolds of quaternionic dimension n <= 14. To do so, we first show that the isometry group Isom(M) of any…
New symplectic singularities from gauge theories
Amihay Hanany, Guhesh Kumaran, Deshuo Liu +1
Families of gauge theories with eight supercharges are found to have a Higgs branch which is an isolated symplectic singularity. These are, in…
Singularities in Calogero--Moser Varieties
Gwyn Bellamy, Ruslan Maksimau, Travis Schedler
In this article we describe completely the singularities appearing in Calogero--Moser varieties associated (at any parameter) to the wreath product symplectic reflection groups. We…
Nonprojective crepant resolutions of quiver varieties
Daniel Kaplan, Travis Schedler
In this paper, we construct a large class of examples of proper, nonprojective crepant resolutions of singularities for Nakajima quiver varieties. These include four and six dimens…
Creating quantum projective spaces by deforming q-symmetric algebras
Mykola Matviichuk, Brent Pym, Travis Schedler
We construct a large collection of "quantum projective spaces", in the form of Koszul, Calabi-Yau algebras with the Hilbert series of a polynomial ring. We do so by starting with t…
The semi-invariant ring as the Cox ring of a GIT quotient
Gwyn Bellamy, Alastair Craw, Travis Schedler
We study GIT quotients whose linearisation map defines an isomorphism between the group of characters of and the Picard group of modulo torsion. Our…
