Univalence conditions for a general integral operator
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 For analytic functions in the open unit disk U, we define a new general integral operator. The main object of the this paper is to study this new integral operator and to determine univalence conditions of it.

Second Hankel determinant for a class of analytic functions defined by q-derivative operator
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019 In this paper, we obtain the estimates for the second Hankel determinant for a class of analytic functions defined by q-derivative operator and subordinate to an analytic function.

On geometrical properties of starlike logharmonic mappings
, 2018 In this paper, we find the radius of the disk Ωr such that every starlike logharmonic mapping f (z) of order α , is starlike in |z| r with respect to any point of Ωr .
