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
The paper presents a systematic inverse‑problem method to construct Bern‑Carrasco‑Johansson (BCJ) numerators for one‑loop five‑gluon amplitudes in pure Yang‑Mills theory, detailing…

Exact CHY Integrand Construction Using Combinatorial Neural Networks and Discrete Optimization
Simeng Li, Yaobo Zhang
Constructing a rational CHY integrand that realizes prescribed physical pole constraints is a discrete inverse problem whose combinatorial complexity grows with multiplicity. We en…
