The master differential equations in the external square momentum p2 for the master integrals of the two-loop sunrise graph, in n-continuous dimensions and for arbitrary values of the internal masses, are derived. The equations are then used for working out the values at p2 = 0 and the expansions in p2 at p2 = 0, in (n− 4) at n → 4 limit and in 1/p2 for large values of p2. ——————————PACS 11.10....
