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 -$\…
Selection rules of canonical differential equations from Intersection theory
Jiaqi Chen
The matrix of canonical differential equations consists of the 1--form coefficients obtained by projecting (+1)--forms onto --…
Towards Systematic Evaluation of de Sitter Correlators via Generalized Integration-By-Parts Relations
Jiaqi Chen, Bo Feng
We generalize Integration-By-Parts (IBP) and differential equations methods to de Sitter correlators related to inflation. While massive correlators in de Sitter spacetime are usua…
