Universally prestarlike functions associated with shell like domain
Universally prestarlike functions associated with shell like domain
In this paper, we introduce universally prestarlikegeneralized functions of order $\vartheta $ with $\vartheta \leq 1$ associated with shell like domain, and we getcoefficient bounds and the second Hankel determinant $|a_{2}a_{4}-a_{3}^{2}|$ forsuch functions.
