Özet

We give closed-form evaluation formulas for the real and imaginary parts of the series ∑∞m,n=1 e2πi(mx−ny) mpnr q (mc+n), c ∈ N, in terms of certain zeta values. Particular choices of x and y lead to evaluation formulas for some Tornheim-type∑∞ 1 m,n=1 and Euler-type ∑∞m,n=1 1 np(mc+n)q double series and their alternating analogues. mpnr (mc+n)q.
