Abstract
In pure SU(2) gauge theory we compute the two-loop coefficient in the relation between the lattice bare coupling and the running coupling defined through the Schroedinger functional. This result is reqiured to relate the latter to the MS-coupling in our programme to compute {alpha}{sub s}. In addition it allows us to implement O(a) improvement of the Schroedinger functional to two-loop order. The two-loop {beta}-function is verified in a perturbative computation on the lattice, and the behavior of expansions in the standard and in the Parisi-improved bare couplings are investigated beyond one loop. ((orig.)).
