A new class of identities for Feynman graph amplitudes, dubbed Schoutenidentities, valid at fixed integer value of the dimension d is proposed. Theidentities are then used in the case of the two loop sunrise graph witharbitrary masses for recovering the second order differential equation for thescalar amplitude in d=2 dimensions, as well as a chained sets of equations forall the coefficients of the expansions in (d-2). The shift from $d\approx2$ to$d\approx4$ dimensions is then discussed.
