Depends on the context[1] :) . Each series resulting from the ζ(n) with n as a negative, odd integer has a single, useful value which can be used in its place when it occurs in equations (physics, chemistry, etc.).

It's embarrassing to see how much one can forget. My mathematical studies lie some 20 years in the past and almost anything about sheaf and germs is lost.
