On Fekete-Szeg\"{o} Problem for Certain Subclasses of Analytic Functions Defined by Generalised Integral Operator

Abstract

By using the function $\mathcal{M}^{m}_{\lambda_{1},\lambda_{2},\ell,d}$ that introduced in \cite{Anessa}, we introduce a new generalised integral operator $I^{m}_{\lambda_{1},\lambda_{2},\ell,d}$. By using this operator, we define new subclasses of analytic functions. For these classes, we obtain several Fekete-Szeg\{o} problems.
