D Then there exists a positive

D Then there exists a positive

**constant**ε = e ( p , D ) depending only on p and D such that if || A || < E ( P , D ) it follows that the operator T + q ( A ) is similar to the operator T and is therefore a spectral operator of scalar ...Page 2439

Since there exists a positive

Since there exists a positive

**constant**Co such that ( sin e 2 cosin ( 0/2 ) ] for 0 5 10 5 7/2 , formula ( 30 ) follows at once . Using ( 27 ) , ( 30 ) , and ( 31 ) , we see that there exists a finite**constant**M ' independent of ε such ...Page 2441

This shows that there exists a finite absolute

This shows that there exists a finite absolute

**constant**c ' such that I ( Q ) < c ' ( 1 + lal ) -n + 1 . Using this inequality and using ( 37 ) , we see that there exists a finite**constant**M " independent of ε such that OVA 4 4 4 ( 43 ) ...### What people are saying - Write a review
