**contains**a sphere S , = S ( P1 , & i ) with 0 < & z < 1/2 . By assumption , the set Ag does not**contain**the open set S ( P1 , & z / 2 ) ; hence the non - void open set An S ( P1 , € 1 / 2 )**contains**a ...Page 56

of the image of any neighborhood G of the element 0 in X

of the image of any neighborhood G of the element 0 in X

**contains**a neighborhood of the element 0 in Y. Since a -- b is a continuous function of a and b , there is a neighborhood M of 0 such that M - MCG .Page 309

The set A S- U - E ; then

**contains**no atoms having measure greater than ε . It will now be shown that every measurable subset B of A**contains**a set F with 0 < u ( F ) Sε . Suppose , on the contrary , that some such set**contains**no set ...### What people are saying - Write a review
