If Xe denotes the characteristic function of the set e in E , and if f is in L2 ( R ) ,

then Xef is in Ly ( R ) L2 ( R ) and f is the

generalized sequence { Xef } . Hence , by Theorem 9 , tf is the

L2 ( M ) ...

If Xe denotes the characteristic function of the set e in E , and if f is in L2 ( R ) ,

then Xef is in Ly ( R ) L2 ( R ) and f is the

**limit**in the norm of L2 ( R ) of thegeneralized sequence { Xef } . Hence , by Theorem 9 , tf is the

**limit**in the norm ofL2 ( M ) ...

That is , Q ( E ) = Q ( E ) implies E = E. Similarly , y ( E ) SQ ( E ) implies ESE . If En
