Abstract

We consider certain pairs (A, T) where A is a (multi)ring and
T ⊆ A is a multiplicative set that generates, by a convenient quotient construction,
a (multi)structure that supports a quadratic form theory: with
some natural hypotheses we generalize constructions previously presented
in [3] and [6]. This also provides some steps towards an abstract formally
real quadratic form theory (non necessarily reduced) were the forms have
general coefficients (non only units).
