Multiscale Loop Vertex Expansion for Cumulants, the $T_3^4$ Model (2211.07233v3)
Published 14 Nov 2022 in math-ph, hep-th, and math.MP
Abstract: We construct cumulants up to a finite order of a tensor field theory perturbed by a quartic term, nicknamed the $T_34$ model. The method we use is the multi-scale loop vertex expansion. We prove analyticity and Borel summability of the cumulants up to finite order.
