Abstract
We show a sufficient condition for the defect $\delta (0,f)$ of an analytic function $f(z) = 1 + \sum_{k=1}^{\infty} c_k z^{n_k}$ in the unit disk with Hadamard gaps to vanish. As a consequence, we find that such $f(z)$ whose characteristic function is sufficiently large has no finite defective value.
