The Clausen's Hypergeometric Function is given by provided $d,…
Stable Functions of Janowski Type
Koneri Chandrasekran, Devasir John Prabhakaran, Priyanka Sangal
A function is said to be stable with respect to if \begin{align*} \frac{s_n(f(z))}{f(z)} \prec \frac{1}{g(z)}, \qquad z\in\mathbb{D}, \en…
On a conjecture for trigonometric sums by S. Koumandos and S. Ruscheweyh
Priyanka Sangal, A. Swaminathan
S. Koumandos and S. Ruscheweyh posed the following conjecture: For and , the partial sum , $…
Geometric properties of Cesaro averaging operators
Priyanka Sangal, A. Swaminathan
In this paper, using positivity of trigonometric cosine and sine sums whose coefficients are generalization of Vietoris numbers, we find the conditions on the coefficient …
On generalized Cesàro stable functions
Priyanka Sangal, A. Swaminathan
The notion of Cesàro stable function is generalized by introducing Cesàro mean of type which give rise to a new concept of generalized Cesàro stable function. As an appli…
Vietoris type theorem related to positivity of trigonometric polynomials
Priyanka Sangal, A. Swaminathan
In this work, a Vietoris type theorem for the positivity of sine and cosine sum for a particular sequence of real numbers is provided. In this connection, the positivity of a parti…
