A characterization of strongly exposed points of the unit ball of \(H^ 1\)
Let \(U\) be the closed unit ball in the Hardy space \(H^ 1(B)\), where \(B\) is the unit ball in \(\mathbb{C}^ n\). The author provides a necessary and sufficient condition for an exposed element \(f\in U\) to be strongly exposed, by using among other things a result on function algebra due to F. \& M. Riesz.
