On the order of the reduction of a point on an abelian variety [PDF]

open access: yes, 2018
.: Consider a point of infinite order on an abelian variety over a number field. Then its reduction at any place v of good reduction is a torsion point.

Boundedness of the p-primary torsion of the Brauer group of products of varieties

open access: yesForum of Mathematics, Sigma
Let k be a field finitely generated over its prime subfield. We prove that the quotient of the Brauer group of a product of varieties over k by the sum of the images of the Brauer groups of factors has finite exponent.

Spatial inversion symmetry breaking of vortex current in a biased-ladder superfluid

open access: yesPhysical Review Research
We investigate the quench dynamics of interacting bosons on a two-leg ladder in the presence of a uniform Abelian gauge field. The model hosts a variety of emergent quantum phases, and we focus on the superfluid biased-ladder phase breaking the Z_{2 ...

Hodge theory of abelian covers of algebraic varieties

open access: yesForum of Mathematics, Sigma
Motivated by classical Alexander invariants of affine hypersurface complements, we endow certain finite dimensional quotients of the homology of abelian covers of complex algebraic varieties with a canonical and functorial mixed Hodge structure (MHS ...

Local André-Oort conjecture for the universal abelian variety [PDF]

open access: yes, 2008
. We prove a p-adic analogue of the André-Oort conjecture for subvarieties of the universal abelian varieties containing a dense set of special points. Let g and n be integers with n ≥ 3 and p a prime number not dividing n. Let R be a finite extension of

Nonnatural automorphisms of the Hilbert scheme of two points of some simple abelian variety [PDF]

open access: yes
We construct nonnatural automorphisms of the Hilbert scheme of two points of some simple abelian variety preserving the big diagonal by considering automorphisms of the n-th product of the abelian varieties.6 pages, minor corrections, to appear in ...

Moduli of abelian varieties in mixed and in positive characteristic [PDF]

open access: yes, 2013
We start with a discussion of CM abelian varieties in characteristic zero, and in positive characteristic. An abelian variety over a finite field is a CM abelian variety, as Tate proved. Can it be CM lifted to characteristic zero?

Comparison of the $μ$-invariants of an abelian variety and its dual abelian variety

open access: yes, 2013
In this note, we compare the dual Selmer groups of an abelian variety with that of its dual over certain large Galois field. We give formula which relates the generalized Iwasawa $μ$-invariants associated with their dual Selmer groups under the natural isogeny.
