Hence we find that for n

Hence we find that for n

**sufficiently**large , each u in Cn is in plT + P ) and that R ( u ; T + P ) = Blu ) . Since Blu ) is clearly the product of the compact operator R ( u ; T ) and a bounded operator , it follows that I + P is a ...Page 2360

It will be shown below that | T''R ( y ; T ) A | } for p in V , and i

It will be shown below that | T''R ( y ; T ) A | } for p in V , and i

**sufficiently**large . From this it will then follow as above that the function f ( u ) R ( u ; T + P ) f is uniformly bounded . It will also be shown that T - v is ...Page 2394
