Mapping properties of the zero-balanced hypergeometric functions

Li-Mei Wang

In the present paper, the order of convexity of z\Gauss(a,b;c;z) is first given under some conditions on the positive real parameters a, b and c. Then we show that the image domain…

On the order of convexity for the shifted hypergeometric functions

Li-Mei Wang

In the present paper, we study the order of convexity of $z\Gauss(a,b;c;z)$ with real parameters $a, b$ and $c$ where $\Gauss(a,b;c;z)$ is the Gaussian hypergeometric function. Fir…

Geometric properties of the shifted hypergeometric functions

Toshiyuki Sugawa, Li-Mei Wang

We will provide sufficient conditions for the shifted hypergeometric function $z_{2} F_{1} (a, b; c; z)$ to be a member of a specific subclass of starlike functions in terms of the complex…

Spirallikeness of shifted hypergeometric functions

Toshiyuki Sugawa, Li-Mei Wang

In the present paper, we study spirallikenss (including starlikeness) of the shifted hypergeometric function $f (z) = z_{2} F_{1} (a, b; c; z)$ with complex parameters $a, b, c,$ where $_2F_1(a,…

An extremal problem for univalent functions

Toshiyuki Sugawa, Li-Mei Wang

For a real constant $b,$ we give sharp estimates of $lo g ∣ f (z) / z ∣ + b ar g [f (z) / z]$ for subclasses of normalized univalent functions $f$ on the unit disk.

Quasiconformal extendibility of integral transforms of Noshiro-Warschawski functions

Ikkei Hotta, Li-Mei Wang

Since the nonlinear integral transforms $J_{α} [f] (z) = \int_{0}^{z} (f^{'} (u))^{α} d u$ and $I_{α} [f] (z) = \int_{0}^{z} (f (u) / u)^{α} d u$ with a complex number $α$ have been introduced, a great numbe…

Variability regions of close-to-convex functions

Takao Kato, Toshiyuki Sugawa, Li-Mei Wang

M. Biernacki gave concrete forms of the variability regions of $z / f (z)$ and $z f^{'} (z) / f (z)$ of close-to-convex functions $f$ for a fixed $z$ with $∣ z ∣ < 1$ in 1936. The forms are, howe…
