These include both one-dimensional and two-dimensional series. Most of these series can be expressed in terms of zeta(2), zeta(3), the Catalan constant G and Cl{2}(pi/3) where Cl{2}(theta) is Clausen's function.AMS-LaTeX v1.2, 24 pagesHigh Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
