Best Approximation Results for Fuzzy-Number-Valued Continuous Functions
(MDPI, 2023-02)
In this paper, we study the best approximation of a fixed fuzzy-number-valued continuous function to a subset of fuzzy-number-valued continuous functions. We also introduce a method to measure the distance between a ...
On various types of density of numerical radius attaining operators
(Taylor and Francis, 2023)
In this paper, we are interested in studying Bishop-Phelps-Bollob´as type properties related to the denseness of the operators which attain their numerical radius. We prove that
every Banach space with a micro-transitive ...
On the Algebras VN(H) and VN(H)(*) of an Ultraspherical Hypergroup H
(Cambridge University PressAustralian Mathematical Society, 2022-12-12)
Let H be an ultraspherical hypergroup and let A(H)
be the Fourier algebra associated with H.
In this paper, we study the dual and the double dual of A(H).
We prove among other things that the subspace of all ...
On the extreme non-Arens regularity of Banach algebras
(WileyLondon Mathematical Society, 2021-07-04)
As is well-known, on an Arens regular Banach algebra all continuous functionals are weakly
almost periodic. In this paper, we show that
1-bases which approximate upper and lower
triangles of products of elements in the ...
Modeling spatial dependencies of natural hazards in coastal regions: a nonstationary approach with barriers
(Springer, 2023)
Natural hazards like floods, cyclones, earthquakes, or, tsunamis have deep impacts on the environment and society causing damage to both life and property. These events can cause widespread destruction and can lead to ...
Families of efficient low order processed composition methods
(Elsevier, 2024-10)
New families of composition methods with processing of order 4 and 6 are presented and analyzed. They are specifically designed to be used for the numerical integration of differential equations whose vector field is ...

Dynamical and numerical analysis of classical multiple roots finding methods applied for different multiplicities
(Springer Nature, 2024-05-08)
The aim of this paper is the study of the robustness of classical methods defined for finding multiple roots with single multiplicity m when they are used for approximating different roots of a function having different ...
Bounded below composition operators on the space of Bloch functions on the unit ball of a Hilbert space
(Springer, 2023-09-04)
Let be the open unit ball of a complex finite or infinite dimensional Hilbert space E and consider the space of Bloch functions on . Using Lipschitz continuity of the dilation map on given by for , where denotes the ...
The Lyrids meteor shower: A historical perspective
(Elsevier Science Direct, 2023-10-26)
The April Lyrid meteor shower is the oldest meteor shower ever recorded continuously throughout history, dating as far back as 687 BC. Before the 20th century, historical sources only provided reports of two years of strong ...
