Bounds for radii of starlikeness and convexity of some special functions
Aktaş, İbrahim; Barıcz, Arpad; Orhan, Halit (2018)In this paper we consider some normalized Bessel, Struve, and Lommel functions of the rst kind and, byusing the Euler{Rayleigh inequalities for the rst positive zeros of a combination of special functions, we obtain ... -
ON NEW SUBCLASSES OF BI-UNIVALENT FUNCTIONS DEFINED BY GENERALIZED SÂLÂGEAN DIFFERENTIAL OPERATOR
Toklu, Evrim; Aktaş, İbrahim; Sağsöz, Fatma (2019)The aim of this investigation is to introduce two new subclasses of the class related with the generalized Sal agean differential operator and find estimates on the coefficients ja2j and ja3j for functions in these new ... -
On Partial Sums of Normalized Error Function
Aktaş, İbrahim (2019)The main purpose of this paper is to determine some lower bounds for real parts of the quotient of normalized error function and its partial sum. In addition, the some upper bounds for absolute values of normalized error ...
