Comment on "Fourier transform of hydrogen-type atomic orbitals'', Can. J. Phys. Vol.\ 96, 724 - 726 (2018) by N. Yükçü and S. A. Yükçü
Ernst Joachim Weniger
Podolsky and Pauling (Phys. Rev. \textbf{34}, 109 - 116 (1929)) were the first ones to derive an explicit expression for the Fourier transform of a bound-state hydrogen eigenfuncti…
Construction of New Generalizations of Wynn's Epsilon and Rho Algorithm by Solving Finite Difference Equations in the Transformation Order
Xiang-Ke Chang, Yi He, Xing-Biao Hu +2
We construct new sequence transformations based on Wynn's epsilon and rho algorithms. The recursions of the new algorithms include the recursions of Wynn's epsilon and rho algorith…
Convergence Analysis of the Summation of the Euler Series by Padé Approximants and the Delta Transformation
Riccardo Borghi, Ernst Joachim Weniger
Sequence transformations are valuable numerical tools that have been used with considerable success for the acceleration of convergence and the summation of diverging series. Howev…
On the Mathematical Nature of Guseinov's Rearranged One-Range Addition Theorems for Slater-Type Functions
Ernst Joachim Weniger
Starting from one-range addition theorems for Slater-type functions, which are expansion in terms of complete and orthonormal functions based on the generalized Laguerre polynomial…
Summation of Divergent Power Series by Means of Factorial Series
Ernst Joachim Weniger
Factorial series played a major role in Stirling's classic book "Methodus Differentialis" (1730), but now only a few specialists still use them. This article wants to show that thi…
The strange history of B functions or how theoretical chemists and mathematicians do (not) interact
Ernst Joachim Weniger
functions are a class of relatively complicated exponentially decaying basis functions. Since the molecular multicenter integrals of the much simpler Slater-type functions are…
