Complete intersections: Moduli, Torelli, and good reduction [PDF]
, 2016 We study the arithmetic of complete intersections in projective space over number fields. Our main results include arithmetic Torelli theorems and versions of the Shafarevich conjecture, as proved for curves and abelian varieties by Faltings. For example,

EBERLEIN–ŠMULYAN THEOREM FOR ABELIAN TOPOLOGICAL GROUPS [PDF]
Journal of the London Mathematical Society, 2004 Leaning on a remarkable paper of Pryce, the paper studies two independent classes of topological Abelian groups which are strictly angelic when endowed with their Bohr topology. Some extensions are given of the Eberlein–ˇSmulyan theorem for the class of topological Abelian groups, and finally, for a large subclass of the latter, Bohr angelicity is ...

Strictly Cyclic Functionals, Reflexivity, and Hereditary Reflexivity of Operator Algebras
Abstract and Applied Analysis, 2012 This paper is concerned with strictly cyclic functionals of operator algebras on Banach spaces. It is shown that if X is a reflexive Banach space and A is a norm-closed semisimple abelian subalgebra of B(X) with a strictly cyclic functional f∈X∗, then A ...

Vanishing Theorems for constructible Sheaves on Abelian Varieties [PDF]
, 2015 We show that the hypercohomology of most character twists of perverse sheaves on a complex abelian variety vanishes in all non-zero degrees. As a consequence we obtain a vanishing theorem for constructible sheaves and a relative vanishing theorem for a ...

Straightening Theorem for bounded Abelian groups
Topology and its Applications, 2008 For any abelian group \(G\), let \(G^{\sharp}\) denote the group \(G\) equipped with its Bohr topology, i. e. the initial topology of \(G\) with respect to the family of all homomorphisms of \(G\) into the circle group. For a positive integer \(m\) and a cardinal \(\kappa,\) let \({\mathbb V}_m^{\kappa}=\bigoplus_{\kappa} {\mathbb Z_m},\) where ...

Freiman's theorem in an arbitrary abelian group [PDF]
Journal of the London Mathematical Society, 2007 A famous result of Freiman describes the structure of finite sets A of integers with small doubling property. If |A + A| <= K|A| then A is contained within a multidimensional arithmetic progression of dimension d(K) and size f(K)|A|. Here we prove an analogous statement valid for subsets of an arbitrary abelian group.

Montel–Type Theorems for Exponential Polynomials
Demonstratio Mathematica, 2016 In this paper, we characterize local exponential monomials and polynomials on different types of Abelian groups and we prove Montel-type theorems for these function classes.

Computing nilpotent quotients in finitely presented Lie rings [PDF]
Discrete Mathematics & Theoretical Computer Science, 1997 A nilpotent quotient algorithm for finitely presented Lie rings over \textbfZ (and \textbfQ) is described. The paper studies the graded and non-graded cases separately. The algorithm computes the so-called nilpotent presentation for a finitely presented,

Abelian theorems for the stieltjes transform of functions, II
International Journal of Mathematics and Mathematical Sciences, 1981 An initial (final) value Abelian theorem concerning transforms of functions is a result in which known behavior of the function as its domain variable approaches zero (approaches ∞) is used to infer the behavior of the transform as its domain variable ...
