The functions totally

**u**-**measurable**on S , or , if u is understood , totallymeasurable on S are the functions in the closure TM ( S ) in F ( S ) of the u -

simple functions . If for every E in { with ulu , E ) < 00 , the product xet off with the

characteristic ...

NCS .

( b ) the function g defined by g ( s ) = f ( s ) if s ¢S + US - , g ( s ) = 0 if se S + US - ,

is

**u**-**measurable**. Next suppose that we consider a function † ( vector orextended real - valued ) which is defined only on the complement of a p - null set

NCS .
