**seen**that Tx exists for each x , and that T is continuous . Thus Lemma 4 shows that T is bounded . Now , when Tx exists , Tx = lim Tnx S lim inf | Tn || ] , n - 00 n - 00 and thus | T | = lim inf Tnl . Finally ...Page 254

Thus by forming the chain UB , UG , ... , Uz ' , Up . it is

Thus by forming the chain UB , UG , ... , Uz ' , Up . it is

**seen**that vg is equivalent to vg , and thus that up is in V. Since { vp } is a basis , the vector Wq has an expansion of the form ug = { ( uq , UB ) UBY Ex ( uq , vBlog , so ...Page 449

Let B , be the dense subset of the boundary B of A at which there are non - zero functionals tangent to A. We have

Let B , be the dense subset of the boundary B of A at which there are non - zero functionals tangent to A. We have

**seen**that ( aA , + ( 1 - a ) An B = $ for 0 < a < 1. Since aA , + ( 1 - a ) A is open , ( aA , + ( 1 - a ) An B = 4 for 0 ...### What people are saying - Write a review
