Since G is an

F1 - 6 ) . If F is a closed set it follows from this inequality , by allowing G , to range

over all open sets containing FF , that Mi ( Fi ) = Mz ( FF ; ) + Mz ( F1 - F ) .

Since G is an

**arbitrary**open set containing Fi - G , we have M ( F1 ) S2 ( G ) + M (F1 - 6 ) . If F is a closed set it follows from this inequality , by allowing G , to range

over all open sets containing FF , that Mi ( Fi ) = Mz ( FF ; ) + Mz ( F1 - F ) .

N ( T ; A , ε ) = { R | R € B ( X , Y ) , | ( T R ) xl < , X € A } where A is an

finite subset of X , and ε > 0 is

generalized sequence { T , } converges to T if and only if { Tex } converges to Tx

for every x in ...
