Let (X0,/to) and (Xi,/ti) be measure spaces. We omit reference to the classes of measurable sets, and all sets used below are assumed measurable even when the assumption is not made explicitly. Let T be a linear transformation from Li (X0,/t0) into Li (Xi,# i) which is positive (that is, takes positive functions into positive functions) and has norm~ 1. There is then an adjoint transformation T* from Loo (Xi,/ti) into L~(Xo,# 0), also positive, with L~ norm~ 1. If/t~ is not a-finite, Loo (Xi,/t~) has the usual lupremum norm but by definition each of its functions vanishes off a set, depending on the function, which is the union of countably many sets of finite measure. The adjoint T* is determined by (1.1) f (T/0) gi d/ti=~/0 T* gi d/t0.
