# Generalised graph Laplacians and canonical Feynman integrals with kinematics

@inproceedings{Brown2022GeneralisedGL, title={Generalised graph Laplacians and canonical Feynman integrals with kinematics}, author={Francis Brown}, year={2022} }

. To any graph with external half-edges and internal masses, we associate canonical integrals which depend non-trivially on particle masses and momenta, and are always ﬁnite. They are generalised Feynman integrals which satisfy graphical relations obtained from contracting edges in graphs, and a coproduct involving both ultra-violet and infra-red subgraphs. Their integrands are deﬁned by evaluating bi-invariant forms which represent stable classes in the cohomology of the general linear group…
