Abstract: | Summary Let A be a real or complex commutative ordered algebra with identity and involution. Let denote the set of positive multiplicative linear functionals on A. Equip with the topology of simple convergence. For a fixed non-negative probability measure on the set
p
of linear functionals f on A which admit an integral representation of the form
with F L
p
( ) (1 p![lE](/content/q8l68230567652p7/xxlarge8806.gif) ) is biuniquely identified with L
p
( ) via the map tf F. The norm on
p
under which this map becomes an isometry is characterized and a formula for approximating F is derived. The linear functionals which admit representation of the form
with ![ngr](/content/q8l68230567652p7/xxlarge957.gif) ![bottom](/content/q8l68230567652p7/xxlarge8869.gif) are also characterized and appropriately normed. The theory is applied to solve abstract versions of trigonometric and n-dimensional moment problems as well as provide an alternate point of view to the theory of L
p-spaces. New proofs of classical theorems are offered.Research for this paper was sponsored in part by the Danish Natural Science Research Council (Grant No.511-10302) and in part by the National Science Foundation (Grant No. MCS78-03397)The results contained herein include the proofs of theorems announced in 15] |
