comment What are some geometric / physical / probabilistic interpretations of the Riemann zeta function at integer arguments n ≤ 1?
on the "in some sense": the -1/12 in string theory is related to the fact that the discriminant function $\Delta$ is modular of weigth 12. It is this fact which is directly related to the Euler characteristic of the moduli of elliptic curves by a first Chern class argument.
