Abstract: In this article, we establish conditions under which certain entire functions represented as infinite products of their positive zeros are α -spiral-like of order cos ( α ) / 2 . The discussion includes several examples featuring special functions such as Bessel, Struve, Lommel, and q -Bessel functions.
