Abstract

In one dimensional quantum mechanics, the all-orders WKB method leads to `quantum periods' which are formal power series in \hbar whose coefficients are certain period integrals.
These periods, which limelight in supersymmetric/string theories, have rich structure and can be computed in a number of ways.
I will discuss a new perspective on them and their computation.
