These equations show that T ( f ) and T ( 1 / f ) are one - to - one operators and that the range of T ( f ) is a

These equations show that T ( f ) and T ( 1 / f ) are one - to - one operators and that the range of T ( f ) is a

**subset**of the domain of T ( 1 / f ) and vice versa . If x is in D ( T ( S ) ) , then x = T ( 1/8 ) T ( f ) x , and so x is ...Page 2256

Since o ( T ) is totally disconnected , each point , in o ( T ) is contained in an arbitrarily small compact

Since o ( T ) is totally disconnected , each point , in o ( T ) is contained in an arbitrarily small compact

**subset**o of o ( T ) which is open in the relative topology of o ( T ) . It follows that the set 7 ( 0 ) = { z | z - 1 € o } is ...Page 2257

Since by assumption | E ( 0 ; T ) | is uniformly bounded for o in K , since each compact open

Since by assumption | E ( 0 ; T ) | is uniformly bounded for o in K , since each compact open

**subset**01 of o ( R ) is either a compact ... R ) ] is uniformly bounded as 0 , runs over the family of all compact open**subsets**of o ( R ) .### What people are saying - Write a review
