Abstract
We use the concept of convolution to introduce and study the properties of a unified family
$\mathcal{TUM}_\gamma(g,b,k,\alpha)$,
$(0\leq\gamma\leq1,\,k\geq0)$,
consisting of uniformly $k$-starlike and $k$-convex functions of
complex order $b\in\mathbb{C}\setminus\{0\}$
and type $\alpha\in[0,1)$.
The family $\mathcal{TUM}_\gamma(g,b,k,\alpha)$ is a generalization of several other families of analytic functions available in literature.
Apart from discussing the coefficient bounds, sharp radii estimates, extreme points and the subordination theorem for this family, we settle down the Silverman's conjecture for integral means inequality. Moreover, invariance of this family under certain well-known integral operators is also established in this paper. Some previously known results are obtained as special cases.
期刊介绍:
JMS - European Journal of Mass Spectrometry, is a peer-reviewed journal, devoted to the publication of innovative research in mass spectrometry. Articles in the journal come from proteomics, metabolomics, petroleomics and other areas developing under the umbrella of the “omic revolution”.
