Moduli of -constellations and crepant resolutions I: the abelian case
Ryo Yamagishi
For a finite abelian subgroup , we study whether a given crepant resolution of the quotient variety is obtained as a moduli space of…
Moduli of -constellations and crepant resolutions II: the Craw-Ishii conjecture
Ryo Yamagishi
For any given finite subgroup , we show that every projective crepant resolution of the quotient variety is isomorphic to the moduli…
Four-dimensional conical symplectic hypersurfaces
Ryo Yamagishi
We show that every indecomposable conical symplectic hypersurface of dimension four is isomorphic to the known one, namely, the Slodowy slice which is transversal to the nilp…
Singularities of Fano varieties of lines on singular cubic fourfolds
Ryo Yamagishi
Let be a cubic fourfold that has only simple singularities and does not contain a plane. We prove that the Fano variety of lines on has the same analytic type of singularit…
Symplectic resolutions of the Hilbert squares of ADE surface singularities
Ryo Yamagishi
We study symplectic resolutions of the Hilbert scheme of two points on a surface with one ADE-singularity. We also characterize such singularities by central fibers of their symple…
On smoothness of minimal models of quotient singularities by finite subgroups of
Ryo Yamagishi
We prove that a quotient singularity by a finite subgroup has a crepant resolution only if is generated by junior elements. This…
Crepant resolutions of a Slodowy slice in a nilpotent orbit closure in
Ryo Yamagishi
One of our results of this article is that every (projective) crepant resolution of a Slodowy slice in a nilpotent orbit closure in can be obtained as…
