On embedding left-ordered groups into division rings

Abstract

We present and discuss methods for embedding a left-ordered group G into the multiplicative group of a skew field D. Among others, we are interested in the case in which any group automorphism of G extends to a ring automorphism of D and we will be able to apply Dubrovin's embedding theorem to a special class of left-ordered groups which we call locally complete.

We would like to thank F. Jakobs and S. Naumann for reading an early draft, suggesting a number of improvements, and pointing out some inaccuracies.
