  Abstract:

For functions $ f(z)$ which are starlike of order $ alpha$, convex of order $ alpha$, and $ lambda$-spiral-like of order $ alpha$ in the open unit disk $ mathbb{U}$, some interesting sufficient conditions involving coefficient inequalities for $ f(z)$ are discussed. Several (known or new) special cases and consequences of these coefficient inequalities are also considered. ;
