On a universal axiomatization of the real closed fields
Krzysztof Jan Nowak (1996)
Annales Polonici Mathematici
This paper presents a natural axiomatization of the real closed fields. It is universal and admits quantifier elimination.

On quotients of the space of orderings of the field ℚ(x)
Paweł Gładki, Bill Jacob (2016)
Banach Center Publications
In this paper we present a method of obtaining new examples of spaces of orderings by considering quotient structures of the space of orderings - it is, in general, nontrivial to determine whether, for a subgroup the derived quotient structure is a space of orderings, and we provide some insights into this problem. In particular, we show that if a quotient structure arising from a subgroup of index 2 is a space of orderings, then it necessarily is a profinite one.
