The exp-log normal form of types [PDF]

open access: yes, 2016
Lambda calculi with algebraic data types lie at the core of functional programming languages and proof assistants, but conceal at least two fundamental theoretical problems already in the presence of the simplest non-trivial data type, the sum type ...

On moments of twisted $L$-functions [PDF]

open access: yes, 2016
We study the average of the product of the central values of two $L$-functions of modular forms $f$ and $g$ twisted by Dirichlet characters to a large prime modulus $q$.

Fast methods to compute the Riemann zeta function [PDF]

open access: yes, 2011
The Riemann zeta function on the critical line can be computed using a straightforward application of the Riemann-Siegel formula, Sch\"onhage's method, or Heath-Brown's method.

On the Voltage Response of Homogeneous Earth Models in Central Loop Electromagnetic Sounding

open access: yesInternational Journal of Antennas and Propagation, 2022
An accurate series-form explicit expression is derived for the voltage induced in the small receiving loop of a central loop electromagnetic sounding system positioned above a homogeneous earth model.

Generalization of the coupled dipole method to periodic structures [PDF]

open access: yes, 2003
We present a generalization of the coupled dipole method to the scattering of light by arbitrary periodic structures. This new formulation of the coupled dipole method relies on the same direct-space discretization scheme that is widely used to study the

The Bombieri-Vinogradov theorem for nilsequences

open access: yesDiscrete Analysis, 2021
The Bombieri-Vinogradov theorem for nilsequences, Discrete Analysis 2021:21, 55 pp. The prime number theorem asserts that the density of the primes in the vicinity of a large integer $n$ is approximately $1/\log n$, or equivalently that the number of ...

Mean square estimate for relatively short exponential sums involving Fourier coefficients of cusp forms [PDF]

open access: yes, 2014
We estimate the mean square of a short exponential sum involving Fourier coefficients of a cusp form with a linear twist, a smooth weight function, and a relatively short averaging interval.Comment: One lemma was wrong, so that is replaced by a different

Multi-Horizon Forecasting of Global Horizontal Irradiance Using Online Gaussian Process Regression: A Kernel Study

open access: yesEnergies, 2020
In the present paper, global horizontal irradiance (GHI) is modelled and forecasted at time horizons ranging from 30 min to 48 h, thus covering intrahour, intraday and intraweek cases, using online Gaussian process regression (OGPR) and online sparse ...

Retracted Article: On the fourth power mean of the two-term exponential sums [PDF]

open access: yesJournal of Inequalities and Applications, 2014
Abstract Abstract The main purpose of this paper is using the analytic methods and the properties of Gauss sums to study the computational problem of one kind of fourth power mean of two-term exponential sums, and to give an interesting identity and asymptotic formula for it.
