Kinematics, cluster algebras and Feynman integrals
Song He, Zhenjie Li, Qinglin Yang
We identify cluster algebras for planar kinematics of conformal Feynman integrals in four dimensions, as sub-algebras of that for top-dimensional corresponding to -poin…

Landau-based Schubert analysis
Song He, Xuhang Jiang, Jiahao Liu +1
We revisit the conjectural method called Schubert analysis for generating the alphabet of symbol letters for Feynman integrals, which was based on geometries of intersecting lines…
