Popis: We study central extensions of division rings with orderings of higher level. We show that orderings extend to certain immediate and inert extensions. Further, it is proven that any n-ordered division ring can be extended to a n-ordered division ring with almost real closed center. In the last section, an old theorem due to Neumann is generalized: every n-ordered division ring can be extended to a n-ordered division ring containing ℝ in its center.
