On Bishop–Phelps and Krein–Milman Properties
Mathematics, 2023 A real topological vector space is said to have the Krein–Milman property if every bounded, closed, convex subset has an extreme point. In the case of every bounded, closed, convex subset is the closed convex hull of its extreme points, then we say that ...

Warsaw Active-Target TPC: A new detector for photonuclear reactions studies at astrophysical energies [PDF]
EPJ Web of Conferences, 2023 An active-target time-projection chamber (TPC) optimised for studying nuclear reactions of astro-physical interest was developed by the University of Warsaw for studying photo-disintegration reactions using intense, monochromatic γ-ray beams.

Preservation of Extreme Points
Mathematics, 2022 We characterize the extreme points of the closed unit ball of the dual of a Banach space which are preserved by the adjoint of any extreme operator. The result is related to the structure topology introduced by Alfsen and Effros on the set of all extreme points in the dual of any Banach space.

A note on multivariate majorization [PDF]
Journal of Mahani Mathematical Research, 2022 A matrix $A$ is said to be multivariate majorized by a matrix $B$, written $A\prec B$, if there exists a doubly stochastic matrix $D$ such that $A = BD$ .

Classification of the extreme points of ${\mathcal L}_s(^2l_{\infty}^3)$ by computation
Karpatsʹkì Matematičnì Publìkacìï, 2022 Let $l_{\infty}^3=\mathbb{R}^3$ be endowed with the supremum norm. In [Comment. Math. 2017, 57 (1), 1-7], S.G. Kim classified the extreme points of the unit ball of ${\mathcal L}_s(^2l_{\infty}^3)$ only using Mathematica 8, where ${\mathcal L}_s(^2l_ ...

Some Properties of Certain Subclass of Meromorphic Functions Associated with $(p , q)$-derivative [PDF]
Sahand Communications in Mathematical Analysis, 2020 In this paper, by making use of $(p , q) $-derivative operator we introduce a new subclass of meromorphically univalent functions. Precisely, we give a necessary and sufficient coefficient condition for functions in this class.

Extreme points of ${\mathcal L}_s(^2l_{\infty})$ and ${\mathcal P}(^2l_{\infty})$
Karpatsʹkì Matematičnì Publìkacìï, 2021 For $n\geq 2,$ we show that every extreme point of the unit ball of ${\mathcal L}_s(^2l_{\infty}^n)$ is extreme in ${\mathcal L}_s(^2l_{\infty}^{n+1})$, which answers the question in [Period. Math. Hungar. 2018, 77 (2), 274-290].

Geometric Invariants of Surjective Isometries between Unit Spheres
Mathematics, 2021 In this paper we provide new geometric invariants of surjective isometries between unit spheres of Banach spaces. Let X,Y be Banach spaces and let T:SX→SY be a surjective isometry.

Extreme and exposed symmetric bilinear forms on the space ${\mathcal L}_{s}(^2 l_{\infty}^2)$
Karpatsʹkì Matematičnì Publìkacìï, 2020 We classify extreme points and exposed points of the unit ball of the space of bilinear symmetric forms on the real Banach space of bilinear symmetric forms on $l_{\infty}^2.$ It is shown that for this case, the set of extreme points is equal to the set ...
