Sir Michael Berry (Univ Bristol) Singularity - dominated strong fluctuations
The fluctuations of a physical quantity can be described by its moments. In many cases, these diverge as an asymptotic parameter becomes large (or small), through the influence of geometric singularities. These large moments are described by power laws whose exponents can be determined from a knowledge of the singularities. Examples are twinkling starlight, the sex life of moths, certain contour integrals, and several properties of spectra in quantum chaology.
