A procedure for constructing peak functions
arXiv:math/0404039
Abstract
We extend Bishop's one-fourth three-fourths principle for constructing peak functions belonging to a uniform algebra to a situation where the ``approximate barriers'' associated with the Bishop construction are not uniformly bounded.
1) Condition (4) of Theorem 1.1 corrected, 2) Lemma 2.2 of the earlier version is redundant
