While the coefficient-bodies \(S_{k,n}=\{(a,b)\in {\mathbb{C}}^ 2:\) \(z+az^ k+bz^ n\in S\}\) of schlicht trinomials are completely known by the independent results of Rahman-Waniurski and Kasten-Schmieder (1979/80), this is not the case so far for certain subclasses such as close-to-convex or starlike trinomials.

Conformal Mappings of Close-to-Convex Domains
Journal of the London Mathematical Society, 1997Let \(f\) be analytic and univalent in the unit disk \(\Delta\) and let \[ L(r,\theta)= \int_0^r|f'(\rho e^{i\theta})|d\rho\quad \text{for}\quad 0\leq ...

The Geometry of Multivalent Close-to-Convex Functions
Proceedings of the London Mathematical Society, 1985\textit{A. E. Livingston} [Trans. Am. Math. Soc. 155, 161-179 (1965; Zbl 0154.081)] defined the class of close-to-convex functions of order p to be the class K(p) of functions F regular in the unit ball \({\mathbb{B}}\) with \(F(0)=0\) such that \(Re(zF'/f)>0\) in some annulus \(\{\) \(z: \rho

A subclass of close-to-convex functions
2013Summary: We obtain coefficient estimates and distortion and growth theorems for certain subclass of close-to-convex functions. The results presented here contain those given in earlier works in some special cases.

We show that the union closed sets conjecture holds for tree convex sets. The union closed sets conjecture says that in every union closed set system, there is an element to appear in at least half of the members of the system. In tree convex set systems, there is a tree on the elements such that each subset induces a subtree.
