Abstract/Summary

Given a Banach space E with a supremum-type norm induced by a collection of operators, we prove that E is a dual space and provide an atomic decomposition of its predual. We apply this result, and some results obtained previously by one of the authors, to the function space B introduced recently by Bourgain, Brezis, and Mironescu. This yields an atomic decomposition of the predual B∗ , the biduality result that B∗0=B∗ and B∗∗=B , and a formula for the distance from an element f∈B to B0 .
