Bounded gaps between primes in number fields and function fields [PDF]

open access: yes, 2014
The Hardy--Littlewood prime $k$-tuples conjecture has long been thought to be completely unapproachable with current methods. While this sadly remains true, startling breakthroughs of Zhang, Maynard, and Tao have nevertheless made significant progress ...

Mixed Rademacher and BPS black holes

open access: yesJournal of High Energy Physics, 2017
Dyonic 1/4-BPS states in Type IIB string theory compactified on K3 × T 2 are counted by meromorphic Jacobi forms. The finite parts of these functions, which are mixed mock Jacobi forms, account for the degeneracy of states stable throughout the moduli ...

Shooting with degree theory: Analysis of some weighted poly-harmonic systems [PDF]

open access: yes, 2014
In this paper, the author establishes the existence of positive entire solutions to a general class of semilinear poly-harmonic systems, which includes equations and systems of the weighted Hardy--Littlewood--Sobolev type.

A note on Diophantine inequalities in function fields [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
We will discuss how the Bentkus–Götze–Freeman variant of the Davenport–Heilbronn circle method can be used to study 𝔽_q[t] solutions to inequalities of the form ord(λ₁p₁ᵏ+...+λₛpₛᵏ-γ)

Distribution of Eigenvalues for the Modular Group [PDF]

open access: yes, 1995
The two-point correlation function of energy levels for free motion on the modular domain, both with periodic and Dirichlet boundary conditions, are explicitly computed using a generalization of the Hardy-Littlewood method. It is shown that ion the limit

Symmetry and Nonexistence of Positive Solutions for Weighted HLS System of Integral Equations on a Half Space

open access: yesAbstract and Applied Analysis, 2014
We consider system of integral equations related to the weighted Hardy-Littlewood-Sobolev (HLS) inequality in a half space. By the Pohozaev type identity in integral form, we present a Liouville type theorem when the system is in both supercritical and ...

Directional operators and mixed norms [PDF]

open access: yes, 2002
We present a survey of mixed norm inequalities for several directional operators, namely, directional Hardy-Littlewood maximal functions and Hilbert transforms (both appearing in the method of rotations of Calderón and Zygmund), $X$-ray transforms, and ...

A new, rearrangement-free proof of the sharp Hardy-Littlewood-Sobolev inequality [PDF]

open access: yes, 2011
We show that the sharp constant in the Hardy-Littlewood-Sobolev inequality can be derived using the method that we employed earlier for a similar inequality on the Heisenberg group.

Distributional versions of Littlewood's Tauberian theorem [PDF]

open access: yes, 2010
We provide several general versions of Littlewood's Tauberian theorem. These versions are applicable to Laplace transforms of Schwartz distributions. We apply these Tauberian results to deduce a number of Tauberian theorems for power series where Ces\`{a}

PRIME SOLUTIONS TO POLYNOMIAL EQUATIONS IN MANY VARIABLES AND DIFFERING DEGREES

open access: yesForum of Mathematics, Sigma, 2018
Let $\mathbf{f}=(f_{1},\ldots ,f_{R})$ be a system of polynomials with integer coefficients in which the degrees need not all be the same. We provide sufficient conditions for which the system of equations $f_{j}(x_{1},\ldots ,x_{n})=0~(1\leqslant j ...
