We characterise the closure in C (R, R) of the algebra generated by an arbitrary finite point-separating set of C functions. The description is local, involving Taylor series. More precisely, a function f # C belongs to the closure of the algebra generated by 1 , ..., r as soon as it has the ``right

The main purpose of this paper is to define types of positive linear functionals on abstract *-algebras, and to characterize them. For that, we introduce an order and an equivalence relation of positive linear functionals defined by GNS-representations. 1993 Academic Press. Inc.
