A new approximate functional equation for Hurwitz zeta function for rational parameter

For Hurwitz zeta function ζ(s, (a/k)) witha = 1,2,3,…,k, we obtain a new simple approximate functional equation (uniform ink andt) in critical strip. Our method should prove to be an alternative approach to Atkinson’s method in dealing with , whereL(s, x) is Dirichlet L-series moduloq and s = σ +it.
