Abstract
In this investigation, we studied a class of Bazileviˇc type close-to-star functions which is defined by a generalized
differential operator. The new class generalizes many known and new subclasses of close-to-star functions. Some of
the investigated properties are the coefficient bounds and the Fekete-Szeg¨o functional. Our results extend some known
and new ones.
