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…

Truncated cluster algebras and Feynman integrals with algebraic letters
Song He, Zhenjie Li, Qinglin Yang
We propose that the symbol alphabet for classes of planar, dual-conformal-invariant Feynman integrals can be obtained as truncated cluster algebras purely from their kinematics, wh…

Bootstrapping octagons in reduced kinematics from cluster algebras
Song He, Zhenjie Li, Yichao Tang +1
Multi-loop scattering amplitudes/null polygonal Wilson loops in super-Yang-Mills are known to simplify significantly in reduced kinematics, where external legs/edg…
