Abstract
The master differential equations in the external square momentum p(2) for the master integrals of the two-loop sunrise graph, in n-continuo us dimensions and for arbitrary values of the internal masses, are der ived. The equations are then used for working out the values at p(2) = 0 and the expansions in p(2) at p(2) = 0, in (n - 4) at n --> 4 limit and in 1/p(2) for large values of p(2).
