Improved upper bound of third order Hankel determinant for Ozaki close-to-convex functions
(Element d.o.o., 2022)
In this paper we improve the upper bound of the third order Hankel determinant for
the class of Ozaki close-to-convex functions. The sharp bound is conjectured.
Hermitian Toeplicz determinants fr the class S of univalent functions
(National Academy of Sciences of the Republic of Armenia, 2021)
Introducing a new method, we give sharp estimates
of the Hermitian Toeplitz determinants of third order for the
class S of functions univalent in the unit disc. The new approach
is also illustrated on some subclasses ...

Coefficient characterization for certain classes of univalent functions
(Bulletin of the Belgian Mathematical Society - Simon Stevin, 2009)
Necessary and sufficient coefficient conditions are established for certain
classes of analytic functions to be univalent in the unit disk. In addition,
characterizations and convolution results are established for these ...

Hankel determinants of second and third order for the class S of univalent functions
(Slovak Academy of Sciences, Mathematical Institute, 2021)
In this paper we give the upper bounds of the Hankel determinants of the second and
third order for the class S of univalent functions in the unit disc.
Coefficient criteria for univalent and close-to-convex functions
(Graduate School of Information Sciences, Tohoku University, 2013)
In this paper, we provide sufficient conditions for constructing univalent analytic functions in the unit disk
jzj < 1. We motivate our results through several examples and compare with the previously known coefficient
...
