New classes of harmonic functions defined by fractional operator
Sakar, Fethiye Müge; Bağcı, Yasemin; Güney, Hatun Özlem (Işık University Press, 2018)In the present study, we introduce an investigation of new subclasses of harmonic functions which are defined by fractional operator. Firstly, using by fractional operator, we define new subclasses of harmonic functions. ... -
New subclasses of bi-univalent functions of complex order associated with hypergeometric functions
Murugusundaramoorthy, Gangadharan; Güney, Hatun Özlem; Kaliyappan, K. Vijaya (Işık University Press, 2021)In the present paper, new subclasses of bi-univalent functions of complex order associated with hypergeometric functions are introduced and coefficient estimates for functions in these classes are obtained. Several new (or ... -
On a new subclass of harmonic meromorphic functions wıth fixed residue ?
Sakar, Fethiye Müge; Güney, Hatun Özlem (Işık University Press, 2014)We use the differential operator Dn,µ ?,?,? to introduce a new class SHn,?,?,? ?,?,?,µ (w, k, ?) of meromorphic harmonic functions with fixed residue ? in Uw. Then we give the coefficient estimates, distortion theorem and ... -
Second Hankel determinant problem for several classes of analytic functions related to shell-like curves connected with Fibonacci numbers
Sokol, Janusz; İlhan, Sedat; Güney, Hatun Özlem (Işık University Press, 2018-01-16)In this paper, we investigate upper bounds for the second Hankel determinant in several classes of analytic functions in the open unit disc, related to shell-like curves and connected with Fibonacci numbers.
