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 ...
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 ...

Sharp bounds of the third Hankel determinant for classes of univalent functions with bounded turning
(Akademie věd České republiky, Matematický ústav, 2022)
We improve the bounds of the third order Hankel determinant for two classes
of univalent functions with bounded turning.
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 ...
Two types of the second Hankel determinant for the class U and the general class S
(University of Tartu Press, Estonia, 2023)
In this paper we determine the upper bounds of the Hankel
determinants of special type H2(3)(f ) and H2(4)(f ) for the general class
of univalent functions and for the class U.
Ground Surface Subsidence Monitoring Using Sentinel-1 in the “Kostolac” Open Pit Coal Mine
(MDPI, 2023)
Open pit coal mining affects surrounding populated areas, resulting in terrain surface deformation. Surface deformation should be monitored as often as possible to control deformations and prevent potential incidents. This ...
