Sharp Bounds on Hankel Determinant of <i>q</i>-Starlike and <i>q</i>-Convex Functions Subordinate to Secant Hyperbolic Functions
In the present paper, using the <i>q</i>-difference operator, we introduce two classes of <i>q</i>-starlike functions and <i>q</i>-convex functions subordinate to secant hyperbolic functions. As functions in these classes have unique characteristic of missing coef...
