Simple proofs of certain inequalities with logarithmic coefficients of univalent functions
Milutin Obradovic, Nikola Tuneski
In this paper we give simple proofs for the bounds (some of them sharp) of the difference of the moduli of the second and the first logarithmic coefficient for the general class of…

Milutin Obradovic, Nikola Tuneski
In this paper we give estimates of the differences and for the class of functions univalent in the unit disc and normalized by . Her…
On certain properties of the class
N. M. Alarifi, M. Obradovic, N. Tuneski

Hankel determinants of second and third order for the class of univalent functions
Milutin Obradović, Nikola Tuneski
In this paper we give the upper bounds of the Hankel determinants of the second and third order for the class of univalent functions in the unit disc.
New upper bounds of the third Hankel determinant for some classes of univalent functions
Milutin Obradovic, Nikola Tuneski
In this paper we give improved, probably not sharp, upper bounds of the Hankel determinant of third order for various classes of univalent functions and conjecture the sharp one.
