Exact couplings and helicity supertraces
Guillaume Bossard, Boris Pioline
In type II string theory compactified on a -dimensional torus down to dimensions, the and four-graviton couplings are known exactly, for all…
Protected couplings and BPS dyons in half-maximal supersymmetric string vacua
Guillaume Bossard, Charles Cosnier-Horeau, Boris Pioline
We analyze four- and six-derivative couplings in the low energy effective action of string vacua with half-maximal supersymmetry. In analogy with an earlier proposal for the…
Indefinite theta series and generalized error functions
Sergei Alexandrov, Sibasish Banerjee, Jan Manschot +1
Theta series for lattices with indefinite signature arise in many areas of mathematics including representation theory and enumerative algebraic geometry. Their modular…
On certain labelled directed graphs of symbolic dynamics
Wolfgang Krieger
We consider families of coded systems that contain the Dyck shifts and that are closed under topological conjugacy. We introduce a notion of hyposynchronization of subshifts. We in…
On the Rankin-Selberg method for higher genus string amplitudes
Ioannis Florakis, Boris Pioline
Closed string amplitudes at genus are given by integrals of Siegel modular functions on a fundamental domain of the Siegel upper half-plane. When the integrand is of rapi…
