- Abstract
- In this article, we study a version of the Bishop-Phelps-Bollobas property. We investigate a pair of Banach spaces (X, Y) such that every operator from X into Y is approximated by operators which attain their norm at the same point where the original operator almost attains its norm. In this case, we say that such a pair has the Bishop-Phelps-Bollobas point property (BPBpp). We characterize uniform smoothness in terms of BPBpp and we give some examples of pairs (X, Y) which have and fail this property. Some stability results are obtained about l(1) and l(infinity) sums of Banach spaces and we also study this property for bilinear mappings. (C) 2016 Elsevier Inc. All rights reserved.
