On the extension of the Erdös-Mordell type inequalities
(Mathematical Inequalities & Applications, 2014)
We discuss the extension of inequality R_A >= c/a * r_b + b/a * r_c to the plane of triangle ABC. Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdos-Mordell ...
Properties of the quantum state arising after the l-photon state has passed trough a linear quantum amplifier
(Publishing House of the Romanian Academy, 2021)
Abstract. We consider the system of N two-level atoms, of which N0 atoms are
unexcited and N1 are excited. This system of N two-level atoms, which forms a linear
quantum amplifier, interacts with a single-mode electromagnetic ...
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.
Some new results for certain classes of univalent functions
(Springer, 2018)
Some results for a classs of subordinate functions
(Faculty of Sciences and Mathematics, University of Niš, Serbia, 2019)
In this article, a class of subordinate functions is introduced. The bounds of the coefficients of
the functions in this class are investigated.
Disk of univalence of the ratio of two analytic functions
(Taylor and Francis Group, 2015)
On the difference of coefficients of univalent functions

Managing rail service life
(Croatian Metallurgical Society, 2014)
The service life Of tails depends especially on the operational loads and speeds on the railway lines; as well as on the rail maintenance policy. There are multiple aspects of rail maintenance optimization. The following ...
