Hankel determinant of second order for inverse functions of certain classes of univalent functions
(Union of Researchers of Macedonia, R. North Macedonia, 2023)
In this paper we determine mainly sharp upper bounds for the Hankel
determinant of second order for the inverse functions of functions from some
classes of univalent functions.
Learning while playing - Througie platform for creating models of spatial structures
(Faculty of Technical Sciences, University of Novi SadSerbian Society for Geometry and Graphics SUGIG, 2023)
The paper shows a way to create a set of tools that allows the construction of different models of spatial deltahedral structures as a result of the game. It is a set of accessories with which participants (school children, ...
Combining size distribution spectrums of ambient aerosols using equivalent optical properties of nanosized particles selected examples from the Bay of Kotor
(16th Photonics Workshop: Kopaonik, March 12-15, 2023)
Atmospheric aerosols in urban areas typically consist of particles of different
diameters, which can range in size from a few nanometers to a few micrometers and can have
a strong impact on human health [1,2]. This ...

Experimental determination of dynamic parameters of heat passage through the facade wall of a weekend cottage on mountain Kopaonik, Serbia
(Faculty of civil engineering and architecture / University of Niš and Serbian academy of sciences and arts - branch in Niš, 2023)
In this paper, using a dynamic RC model for heat transfer in a room on the ground floor,
the three-time constants of heat transfer that corresponds to the different parts of a
weekend cottage on Kopaonik were determined. ...
A note on r-circulant matrices involving generalized Narayana numbers
(Journal of Mathematical Inequalities, 2023)
In order to further connect structured matrices and integer sequences, r-circulant matrices involving the generalized Narayana numbers are considered. Estimates for spectral norms bounds of such matrices are presented and ...
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.
On a special class of Schwartz functions

Between graphical zonotope and graph-associahedron
(Turkish Journal of Mathematics, 2023)
This manuscript introduces a finite collection of generalized permutohedra associated to a simple graph. The first polytope of this collection is the graphical zonotope of the graph and the last is the graph–associahedron ...
H-colouring revisited
(Faculty of Sciences and Mathematics, Department of Mathematics, 2023)
In this paper we give a new, shortened proof of NP-completeness of CSP problem for undirected, non bipartite graphs, of interest for generalization to QCSP problem. We also give some illustrative examples.
