On a Numerical Radius Preserving Onto Isometry on L(X)
Journal of Function Spaces, 2016 We study a numerical radius preserving onto isometry on L(X). As a main result, when X is a complex Banach space having both uniform smoothness and uniform convexity, we show that an onto isometry T on L(X) is numerical radius preserving if and only if ...

The Ising model with long-range interactions
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015 The phase transition in the two-dimensional and three-dimensional Ising models with long-range spin interactions are studied with the Monte-Carlo method. The interaction region between spins is characterized by the radius $R$.

Schur product of matrices and numerical radius (range) preserving maps
Linear Algebra and its Applications, 2007 Let \(M_n\) (resp., \(H_n)\) be the algebra of \(n\)-by-\(n\) complex matrices (resp., Hermitian matrices). The numerical range \(W(A)\) and numerical radius \(w(A)\) of \(A\) in \(M_n\) are given by \[ W(A)=\{x^*Ax: x\in\mathbb{C}^n,x^*x=1\}\quad\text{and} \quad w(A)=\max\{|\lambda|: \lambda\in W(A)\}, \] respectively.

Matricial Radius: A Relation of Numerical radius with Matricial Range
, 2019 It has been shown that if $T$ is a complex matrix, then {\small\begin{align*} (T)&=\frac{1}{n}\sup\left\{|\mathrm{Tr}\ X|;\ X\in W^n(T)\right\}\\ &=\frac{1}{n}\sup\left\{\|X\|_1;\ X\in W^n(T)\right\}\\ &= \sup\left\{ (X);\ X\in W^n(T)\right\} \end{align*} } where $n$ is a positive integer, $ (T)$ is the numerical radius and $W^n(T)$ is

Hydraulic Calculations of a Telescopic Water Intake
Slovak Journal of Civil Engineering, 2023 Telescopic water intake structures allow for the selective intake of water from the top layers of a reservoir. A telescopic water intake has a high degree of mobility, and a wide field of application; at the same time, it is very simple and convenient to
