D-instanton perturbation theory by Ashoke Sen

“…This causes a breakdown of the Siegel gauge, but a different gauge fixing consistent with the BV formalism renders the perturbation theory finite and unambiguous. At each order, this produces extra contribution to the amplitude besides what is obtained from integration over the moduli space of Riemann surfaces.…”

Flow-oriented perturbation theory by Michael Borinsky, Zeno Capatti, Eric Laenen, Alexandre Salas-Bernárdez

“…Abstract We introduce a new diagrammatic approach to perturbative quantum field theory, which we call flow-oriented perturbation theory (FOPT). Within it, Feynman graphs are replaced by strongly connected directed graphs (digraphs). …”

Applications Of Perturbation Theory To Acoustic Logging by Ellefsen, K. J., Cheng, C. H.

“…For guided wave propagation in boreholes, perturbation theory is used to calculate (1) the partial derivative of the wavenumber or frequency with respect to an elastic modulus or density, (2) group velocity, and (3) the effect of a borehole with a slightly irregular cross section upon the phase velocity. …”
