| چکیده | ||
| Considering two special families of regular functions in an open unit disk based on quasi-subordination, we present sharp bounds for initial coefficient estimates and also determine the classical functional of Fekete-Szegö of functions in these families. Further, we discuss subordination and majorization results for the associated families. Few known and several new consequences are established. | ||
