High precision computation and a new asymptotic formula for the generalized Stieltjes constants

Sandeep Tyagi

We provide an efficient method to evaluate the generalized Stieltjes constants numerically to arbitrary accuracy for large and values. The method uses an i…

Double Exponential method for Riemann Zeta, Lerch and Dirichlet L-functions

Sandeep Tyagi

We provide efficient methods to evaluate the Riemann zeta, the Lerch zeta and the Dirichlet -functions. The method uses the Riemann-Siegel (RS) type formulas and a modified doub…

A new integral representation for the Riemann Zeta function

Sandeep Tyagi, Christian Holm

A new integral representation for the Riemann zeta function is derived. This representation covers the important region of the complex plane where the real part of the argument of…

Evaluation of Coulomb potential in a triclinic cell with periodic boundary conditions

Sandeep Tyagi

Lekner and Sperb's work on the evaluation of Coulomb energy and forces under periodic boundary conditions is generalized that makes it possible to use a triclinic unit cell in simu…

Rapid evaluation of the periodic Green's function in d dimensions

Sandeep Tyagi

A method is given to obtain the Green's function for the Poisson equation in any arbitrary integer dimension under periodic boundary conditions. We obtain recursion relations which…
