**COROLLARY**. For every x # 0 in a normed linear space X , there is an x * € X * with 122 * 1 = 1 and x * x lxl . PROOF . Apply Lemma 12 with Y = 0. The x * required in the present**corollary**may then be defined as x | times the æ ...Page 188

**Corollary**6 is obtained by taking ( Si , Ei , Mi ) to be the Borel - Lebesgue measure on the real line for i = 1 , ... , n . Then S = P_ Si is n - dimensional Euclidean space , and u = MX .Page 662

**COROLLARY**. When the strong limit E = lim , A ( n ) erists it is a projection of X upon the manifold { x \ Tx = x } of fixed points of T. The complementary projection has the closure of ( I – T ) X for its range . PROOF .### What people are saying - Write a review
