p-Adic BMO and VMO functions

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
Spaces of p-adic BMO and VMO functions are considered. It is proved that locally constant functions are dense in VMO space under BMO norm.

BMO Spaces on Weighted Homogeneous Trees [PDF]

open access: yesThe Journal of Geometric Analysis, 2020
We consider an infinite homogeneous tree $\mathcal V$ endowed with the usual metric $d$ defined on graphs and a weighted measure $ $. The metric measure space $(\mathcal V,d, )$ is nondoubling and of exponential growth, hence the classical theory of Hardy and $BMO$ spaces does not apply in this setting.

$BMO$ Spaces for Laguerre Expansions [PDF]

open access: yesTaiwanese Journal of Mathematics, 2012
Let $\{\varphi_n^{\alpha}\}_{n\in \mathbb{N}}$ be the Laguerre functions of Hermite type with index $\alpha$. These are eigenfunctions of the Laguerre differential operator $L_\alpha=\dfrac{1}{2}(-\frac{d^2}{dy^2}+y^2+\frac{1}{y^2}(\alpha^2-\frac{1}{4}))$.

The BMO-Dirichlet problem for elliptic systems in the upper half-space and quantitative characterizations of VMO [PDF]

open access: yesAnalysis & PDE, 2016
We prove that for any homogeneous, second order, constant complex coefficient elliptic system $L$, the Dirichlet problem in $\mathbb{R}^{n}_{+}$ with boundary data in BMO is well-posed in the class of functions $u$ with $d\mu_u(x',t):=|\nabla u(x',t)|^2\,

Boundedness and Compactness of Hankel Operators on Large Fock Space

open access: yesJournal of Function Spaces, 2022
We introduce the BMO spaces and use them to characterize complex-valued functions f such that the big Hankel operators Hf and Hf¯ are both bounded or compact from a weighted large Fock space Fpϕ into a weighted Lebesgue space Lpϕ when 1 ...

Variable λ-Central Morrey Space Estimates for the Fractional Hardy Operators and Commutators

open access: yesJournal of Mathematics, 2022
This paper aims to show that the fractional Hardy operator and its adjoint operator are bounded on central Morrey space with variable exponent. Similar results for their commutators are obtained when the symbol functions belong to λ-central bounded mean ...

Exploiting an Elitist Barnacles Mating Optimizer implementation for substitution box optimization

open access: yesICT Express, 2023
Barnacles Mating Optimizer (BMO) is a new metaheuristic algorithm that suffers from slow convergence and poor efficiency due to its limited capability in exploiting the search space and exploring new promising regions. Addressing these shortcomings, this
