Accounting of cross-sectional deformation of the contour in the calculation of thin-walled rods
Trudy Odesskogo Politehničeskogo Universiteta, 2014 One of the main hypotheses in the calculation of thin-walled rods theory is the assumption that there is no deformation of the contour of the cross section.

Targeting multi-loop integrals with neural networks
SciPost Physics, 2022 Numerical evaluations of Feynman integrals often proceed via a deformation of the integration contour into the complex plane. While valid contours are easy to construct, the numerical precision for a multi-loop integral can depend critically on the ...
