The generalized one is known as the Hurwitz function and the most common form of it can be expressed as a p-series. Its value at 2 is pi squared over si, and it can be computed at all even positive integers greater than 2, but its values at odd positive integers are not known. All of its nontrivial zeroes may have real part one-half and the Clay Mathematics Institute will pay you a million dollars to prove that. For ten points, name this mathematical function named for a German mathematician and a certain Greek letter.
