. Conversely , since $ ( EU EZ ) = $ ( EU $ ( Eg ) and $ ( EEZ ) = $ ( E2 ) ( EZ ) if

Ez , E , belong to E , v ( uz , ° ( E ) ) is a nonnegative additive set function defined

**follows**readily from the definition of v ( ug ) that v ( 417 , 6 - 1 ( E ) ) 2 0 ( 42 , E ). Conversely , since $ ( EU EZ ) = $ ( EU $ ( Eg ) and $ ( EEZ ) = $ ( E2 ) ( EZ ) if

verify that it is an isomorphism , it will suffice to show that E ( 0 ) = 0 only when o

is the void set $ . Now if E ( 0 ) = 0 , then Xo = { 0 } and o ( T . ) = $ . It

**follows**from Theorem 10 that the map o → E ( 0 ) is a homeomorphism . Toverify that it is an isomorphism , it will suffice to show that E ( 0 ) = 0 only when o

is the void set $ . Now if E ( 0 ) = 0 , then Xo = { 0 } and o ( T . ) = $ . It

COROLLARY . In a reflexive space , the averages A ( a ) are strongly convergent

if they are bounded and if T ( n ) / n converges to zero strongly . PROOF . This
