Since every real

**measurable function**is the difference of two non- negative**measurable functions**, it follows from the theorem that [*] j£ g(s)l(ds) = jE f(s)g(s)t*(ds), E e Z, for a real

**measurable function**g. Since the real and imaginary parts ofa ...

Then T maps fi-

equivalent functions into fi-equivalent functions. Furthermore T is a continuous

linear map of the F-space M(S) = M(S, E, ft, X) of all devalued fi-
