MUMFORD-TATE GROUPS FAMILIES OF CALABI-YAU VARIETIES ANALOGUE ANDR E-OORT PROBLEMS I
2018/4/20
We study Mumford-Tate groups of families of Calabi-Yau manifolds in this notes, for example, we have interest in the relations between the geometry of families of Calabi-Yau manifolds and their Mumfor...

AN ANALYTIC CONSTRUCTION OF THE DELIGNE-MUMFORD COMPACTIFICATION OF THE MODULI SPACE OF CURVES
ANALYTIC CONSTRUCTION DELIGNE-MUMFORD COMPACTIFICATION MODULI SPACE OF CURVES
2015/8/26
In 1969, P. Deligne and D. Mumford compactified the modulispace of curves Mg,n. Their compactification Mg,n is a projective algebraic variety, and as such, it has an underlying analytic structure. Alt...
Toric Deligne-Mumford stacks and the better behaved version of the GKZ hypergeometric system
Toric Deligne-Mumford stacks GKZ hypergeometric system Algebraic Geometry
2012/5/9
We generalize the combinatorial description of the orbifold (Chen--Ruan) cohomology and of the Grothendieck ring of a Deligne--Mumford toric stack and its associated stacky fan in a lattice $N$ in the...
On the Mumford-Tate conjecture for 1-motives
Mumford-Tate conjecture Number Theory Algebraic Geometry
2011/9/21
Abstract: We show that the statement analogous to the Mumford-Tate conjecture for abelian varieties holds for 1-motives on unipotent parts. This is done by comparing the unipotent part of the associat...
G-graded Castelnuovo Mumford Regularity
G-graded Castelnuovo Mumford Regularity Commutative Algebra Algebraic Geometry
2011/9/5
Abstract: We develop a general graded variant of Castelnuovo-Mumford regularity for modules over a commutative ring $R$ graded by a finitely generated abelian group $G$. With this aim, we establish a ...
Quivers of sections on toric Deligne-Mumford stacks
Quivers of sections toric Deligne-Mumford stacks
2011/1/21
Starting from a collection of line bundles on a smooth projective toric DM stack,we give a stacky analogue of the classical linear series construction. We apply our construction to recover the finite ...
Matchings, coverings, and Castelnuovo-Mumford regularity
Matchings coverings Castelnuovo-Mumford regularity
2010/12/6
We show how co-chordal covers of the edges of a graph give upper bounds on the Castelnuovo-Mumford regularity of its edge ideal. The proof is by an easy application of a deep result of
Kalai and Mesh...
The symplectic Deligne-Mumford stack associated to a stacky polytope
symplectic Deligne-Mumford stack stacky polytope
2010/12/8
We discuss a symplectic counterpart of the theory of stacky fans. First, we define a stacky
polytope and construct the symplectic toric Deligne–Mumford stack associated to it. Then we establish a rel...
