Abstract

We utilize quasi-subordination to analyze and introduce several new classes, and we construct a new operator by combining the error function and q -convolution. Additionally, we obtain estimates for the Fekete Szego functional and the Taylor–Maclaurin coefficients for functions in c 2 and c 3 new classes. Moreover, we discuss some applications of the operator.
