Then , retracing the steps of the above argument , we can conclude that ( I – Ex ) TE , = 0 for each à in C. Hence T leaves the

Then , retracing the steps of the above argument , we can conclude that ( I – Ex ) TE , = 0 for each à in C. Hence T leaves the

Then ( E ( Q ) U ) x = ( 1 - E ( { 2 } ) ( 21 – T ) ) x ( 21 –T ) x which shows that the

Then ( E ( Q ) U ) x = ( 1 - E ( { 2 } ) ( 21 – T ) ) x ( 21 –T ) x which shows that the
