The bi-adjoint scalar -loop planar integrand recursion and graded inverse variables
Yi-Xiao Tao
Previously in \cite{Tao:2025fch}, we constructed the -loop planar integrands using loop components and loop kernels by some recursion rules. In this paper, we propose a new f…

Elliptic modular graph forms, equivariant iterated integrals and single-valued elliptic polylogarithms
Oliver Schlotterer, Yoann Sohnle, Yi-Xiao Tao
The low-energy expansion of genus-one string amplitudes produces infinite families of non-holomorphic modular forms after each step of integrating over a point on the torus worldsh…
