چکیده
|
In this paper, we introduce a newly defined subclass sσ(ϑ, γ, η; φ) of bi-univalent functions by using the tremblay differential operator satisfying subordinate conditions in the unit disk. moreover, we use the faber polynomial expansion to derive bounds for the feketeszegö problem and first two taylor-maclaurin coefficients |a2| and |a3| for functions of this class.
