The canonical differential equations of the one-loop-like integrals
Jiaqi Chen, Bo Feng, Liang Zhang
Recently, a new approach for high loop integrals has been proposed in \cite{Huang:2024nij}, where the whole parameter integration has been divided into two parts: a one-loop-like i…

Multivariate hypergeometric solutions of cosmological (dS) correlators by -form differential equations
Jiaqi Chen, Bo Feng, Yi-Xiao Tao
In this paper, we give the analytic expression for the homogeneous part of solutions of arbitrary tree-level cosmological correlators, including massive propagators and time-deriva…

Notes on Selection Rules of Canonical Differential Equations and Relative Cohomology
Jiaqi Chen, Bo Feng
We give an explanation of the -form of the coefficient matrix of canonical differential equations using the projection of (+1)- forms onto -$\…
