Abstract: In this talk I discuss properties of the two Symanzik polynomials whichcharacterise the integrand of an arbitrary multi-loop integral in its Feynmanparametric form. Based on the construction from spanning forests and Laplacianmatrices, Dodgson-s relation is applied to derive factorisation identitiesinvolving both polynomials. An application of Whitney-s 2-isomorphism theoremon matroids is discussed.
