Spaces of Orderings, to stress the connection with the duality of topological groups and the theory of reduced quadratic forms. Section 2 is devoted to sums and extensions of spaces of orderings and their basic properties. In Section 3 we introduce spaces of finite type and their trees, which support the use of inducti

The Main Results, reduce to the corresponding problems in the spaces of orderings .* associated to the subvarieties . of .. This general principle is proved in Sections 1, 2 and 3. Also, in Sections 1 and 2, we obtain criteria for a set to be basic open or to be principal open, and extend to . the inequalities among

Spaces of Signs of Rings,ce of signs of a ring reduces to estimations of the size of fans of residue fields of that ring. We obtain in Section 1 such estimations, via real valuations, after proving the so-called trivialization theorem for fans. Then, in Section 2, we deduce upper bounds for the stability index of a field ex

Very few proofs are given, since almost everything can be found in our general references [Mt] and the more elementary [At-Mc], [Bs-Is-Vg]; an important exception is our proof that local-ind-etale limits of excellent rin

We review there several classical results in the framework of real spaces, with some technical suplements that will be needed later. In Section 4 we obtain the algebraic properties of the vari

These rings have two special features: firstly, their complexity bounds are low, and, secondly, generation of basic sets and separation are characterized by multilocal conditions. We end in Section 7 with the tra

Using these, we bound each invariant ., $ar s$, ., $ar t$, . in terms of any of the others. In particular, all of them are finite
