Riemann-Liouville fractional derivative with varying arguments


N. Ravikumar, S. Latha




In this paper, we define the subclasses $\mathcal{V_\delta}(A,B)$ and $\mathcal{K_\delta}(A,B)$ of analytic functions by using $\Omega^{\delta}f(z)$. For functions belonging to these classes, we obtain coefficient estimates, distortion bounds and many more properties.
