Abstract

In strongly deformed planar N=4 super-Yang-Mills theory, or fishnet theory, a point-split single-trace correlation function of four dimension-m scalar operators is given by a single Feynman integral, which involves integrating over locations of a m×m grid of points. We show that for any integer m this square fishnet graph is invariant under the combined action of a kinematic map and the antipode map of the Hopf algebra on multiple polylogarithms; i.e. it possesses an antipodal self-duality.
