New classes of harmonic functions defined by fractional operator
(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. ...
Second Hankel determinant problem for several classes of analytic functions related to shell-like curves connected with Fibonacci numbers
(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.
