Abstract: It is known that the set of boundary zeros of a function, analytic in the unit disc and with derivative in the Hardy class ${H^p}$, is a Carleson set provided $p > 1$. In this paper a proof is given which includes the case $p = 1$. Peak sets for such functions are investigated and sufficient conditions on subsets of the boundary are given, which guarantee that they are peak sets.
