Abstract

In the present note it is shown that for a set of positive integers $\wedge$ a Müntztype condition holds if and only if there exists a lacunary power series $f(z)=\sum\limits_{v\in\wedge} f_v/z^v$ that allows an analytic and bounded continuation to the complement of a closed logarithmical sector with vertex at the origin.
