High-energy string amplitudes have asymptotic expansions governed by Bernoulli numbers, upgraded via resurgence to transseries whose Stokes data encode non-perturbative monodromy between kinematic regions.
The Mellin partial wave for four-graviton scattering in supergravity is recast as a rank-two twisted period system of weighted integrals that satisfy first-order differential equations and a recursion with the number of supersymmetries.
Contour equivalence in Feynman parameterization yields universal reduction formulas for one-loop integrals without integration-by-parts.
