On the difference of coefficients of univalent functions
(Faculty of Sciences and Mathematics, University of Niš, Serbia, 2021)
Tilings with diamond, star and pineapple shapes based on the geometry of the regular pentagon
(Serbian Society for Geometry and Graphics (SUGIG)Faculty of Mechanical Engineering, University of Belgrade, 2021)
This paper presents a gallery of tessellations created by combining the following equilateral shapes: diamonds and stars, which can be further assembled into a pineapple shape. These three shapes can be decomposed into ...
Pentagon-based radial tiling with triangles and rectangles and its spatial interpretation
(Faculty of Applied Arts, University of Arts in Belgrade, Serbia, 2021)
The paper considers a type of radial pentagon-based tiling consisted of two shapes: triangle
and rectangle. The obtained solution has a spatial interpretation in a 3D arrangement of
equilateral triangles and squares ...
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.
On the fifth coefficient for the class U(lambda)
