摘要：

Let E be a nonseparable rearrangement invariant space, and let E-0 denote the closure of the set of all bounded functions in E. We study elements of E orthogonal to the subspace E-0, i.e., elements x is an element of E such that parallel to x parallel to(E) <= parallel to x + y parallel to(E) for any y is an element of E-0.
