Abstract
We prove the Horrocks theorem for unstable even-dimensional orthogonal Steinberg groups. The Horrocks theorem for Steinberg groups is one of the principal ingredients needed for the proof of the -analogue of Serre's problem, positive solution of which currently is only known in the linear case.
