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.

β¦ Synopsis
Let H(ID) denote the set of analytic functions in the unit disk ID of the complex plane, endowed with the topology of uniform convergence on compact subsets of ID. Let A denote the space of continuous linear functionals over H(ID). In this paper we obtain a characterization of those i E A such that
where B is a fixed function in H ( Q . We also include a discussion of the sharpness of this characterization and an application to some extremal problem concerning A .

There are occasions when a linear autonomous functional differential equation of mixed type can be reduced to a neutral or retarded equation. A necessary condition for such reducibility is shown to be that the set of solutions of the characteristic equation is bounded on the right in the complex pla
