Algebraic versus physical uniqueness of MHV gravity numerators
Lin Mai, Yaobo Zhang
We study whether a tree-level MHV gravity numerator is determined by its degree and by vanishing on for every pair. A flag-variety standard-monomial basi…

An adaptive inverse-problem framework for one-loop five-gluon BCJ numerators
Lin Mai, Yaobo Zhang
An inverse problem comprises a matrix equation together with its unknown space, physical data, equivalence relation, and validation tests. We formulate Bern--Carrasco--Johansson (B…
