Lipschitz continuity of the dilation of Bloch functions on the unit ball of a Hilbert space and applications
(Springer, 2024-02-13)
Let BE be the open unit ball of a complex finite- or infinite-dimensional Hilbert space.
If f belongs to the space B(BE ) of Bloch functions on BE , we prove that the dilation
map given by x → (1 − x 2)R f (x) for x ∈ ...
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 ...
Spatio-temporal modeling of traffic accidents incidence on urban road networks based on an explicit network triangulation
(Taylor and Francis GroupTaylor and Francis, 2022-07-29)
Traffic deaths and injuries are one of the major global public health concerns. The present study considers accident records in an urban environment to explore and analyze spatial and temporal in the incidence of road ...
Clustering constrained on linear networks
(Springer, 2023)
An unsupervised classification method for point events occurring on a geometric network is proposed. The idea relies on
the distributional flexibility and practicality of random partition models to discover the clustering ...
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 ...
Continuous Selections and Extremally Disconnected Spaces
(MDPI, 2023)
This paper deals with extremally disconnected spaces and extremally disconnected Pspaces. A space X is said to be extremally disconnected if, for every open subset V of X, the closure
of V in X is also an open set. P-spaces ...
On the basins of attraction of a one-dimensional family of root finding algorithms: from Newton to Traub
(Springer, 2023)
In this paper we study the dynamics of damped Traub’s methods Tδ when applied to polynomials. The family of damped Traub’s methods consists of root finding algorithms which
contain both Newton’s (δ = 0) and Traub’s method ...
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 ...
Order of products of elements in finite groups
(WileyLondon Mathematical Society, 2018-10)
If G is a finite group, p is a prime, and x∈G, it is an interesting problem to place x in a convenient small (normal) subgroup of G, assuming some knowledge of the order of the products xy, for certain p‐elements y of G.
