Hankel inequalities for bounded turning functions in the domain of cosine Hyperbolic function

Hankel inequalities for bounded turning functions in the domain of cosine Hyperbolic function

In the present article, we define and investigate a new subfamily of holomorphic functions connected with the cosine hyperbolic function with bounded turning. Further some interesting results like sharp coefficients bounds, sharp Fekete-Szegö estimate, sharp $ 2^{nd} $ Hankel determinant and non-sha...
