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 ...
Integer points enumerator of hypergraphic polytopes
(Mathematical Institute of the Serbian Academy of Sciences and Arts, 2021)
For a hypergraphic polytope there is a weighted quasisymmetric
function which enumerates positive integer points in its normal fan
and determines its f −polynomial. This quasisymmetric function
invariant of hypergraphs ...
Weighted P-partitions enumerator
(Applicable Analysis and Discrete Mathematics, 2021)
To an extended generalized permutohedron we associate the weighted integer points enumerator, whose principal specialization is the f-polynomial. In the case of poset cones it refines Gessel's P-partitions enumerator. We ...
The third logarithmic coefficients for the class S
(Scientific and Technological Research Council of Turkey (TUBITAK) - Turkish Academic Network and Information Center (ULAKBIM), 2020)
In this paper we give an upper bound of the third logarithmic coefficient for the class $\mathcal{S}$ of univalent functions in the unit disc.
On the difference of coefficients of univalent functions
(Faculty of Sciences and Mathematics, University of Niš, Serbia, 2021)
On the fifth coefficient for the class U(lambda)
(Union of Researchers of Macedonia, R. North Macedonia, 2021)
Third Hankel determinant for univalent starlike functions
(Springer, 2021)
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.
Sharp upper bounds for initial coefficients and second Hankel determinants
(Korean Mathematical Society, 2020)
On the initial coefficients for certain class of functions analytic in the unit disc
(Rocky Mountain Mathematics Consortium, 2020)
