Riemann surfaces for KPZ with periodic boundaries

Blog Article

The Riemann surface for polylogarithms of half-integer index, which has the topology of an infinite dimensional hypercube, is studied Weekender in relation to one-dimensional KPZ universality in finite volume.Known exact results for fluctuations of the KPZ height with periodic boundaries are expressed in terms of meromorphic functions on this Riemann surface, summed over all the Bento Boxes sheets of a covering map to an infinite cylinder.Connections to stationary large deviations, particle-hole excitations and KdV solitons are discussed.
