Double exponential transformation for computing three-center nuclear attraction integrals
Molecular Physics, 2019 Three-centre nuclear attraction integrals, which arise in density functional and \textit{ab initio} calculations, are one of the most time-consuming computations involved in molecular electronic structure calculations. Even for relatively small systems, millions of these laborious calculations need to be executed.

Criteria for the Application of Double Exponential Transformation
, 2017 The double exponential formula was introduced for calculating definite integrals with singular point oscillation functions and Fourier-integrals. The double exponential transformation is not only useful for numerical computations but it is also used in different methods of Sinc theory.

A Double Exponential Formula for the Fourier Transforms
Publications of the Research Institute for Mathematical Sciences, 2005 From the introduction: We propose a new efficient method that is applicable for the computation of the Fourier transform of a function which may possess a singular point or slowly convergence infinity. The proposed method is based on a generalization of the method of the double exponential (DF) formula. Although it is a widely applicable formula, it is
