On generalized Cesàro stable functions

Abstract

The notion of Ces\`aro stable function is generalized by introducing Ces\`aro mean of type $(b-1;c)$ which give rise to a new concept of generalized Ces\`aro stable function. As an application of generalized Ces\`aro stable functions we also prove for a convex function of order $\lambda\in[1/2,1)$, its Ces\`aro mean of type $(b-1;c)$ is close-to-convex of order $\lambda$. Further two conjectures are also posed in the direction of generalized Ces\`aro stable function. Some particular cases of these conjectures are also discussed.
