Interpolation inequalities between Lorentz space and BMO: the endpoint case (L^{1,infinity}, BMO)

Electronic Journal of Differential Equations, 2019
We prove interpolation inequalities by means of the Lorentz norm, BMO norm, and the fractional Sobolev norm. In particular, we obtain an interpolation inequality for $(L^{1,\infty}, BMO)$, that we call the endpoint case.

Exploiting an Elitist Barnacles Mating Optimizer implementation for substitution box optimization

ICT 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

The Weighted Lp and BMO Estimates for Fractional Hausdorff Operators on the Heisenberg Group

Journal of Function Spaces, 2020
In the setting of Heisenberg group, we characterize those functions Φ, for which the fractional Hausdorff operators TΦ,β and Hausdorff operators TΦ, T˜Φ are bounded on Lp spaces with power weights, BMO space, and Hardy spaces, respectively.

The Hankel operators and noncommutative BMO spaces [PDF]

Annals of Functional Analysis, 2016
Let M be a von Neumann algebra with a faithful normal semifinite trace τ. The noncommutative Hardy space Hp(M) associates with A, which is a subdiagonal algebra of M. We define the Hankel operator Ht on Hp(M), and we obtain that the norm ‖Ht‖ is equal to d(t;A) and is also the equivalent of the BMO(Msa) norm of t for every t∈M, where Msa are the self ...

A characterization of $${{\mathrm{BMO}}}$$ BMO self-maps of a metric measure space [PDF]

Collectanea Mathematica, 2014
This paper studies functions of bounded mean oscillation (BMO) on metric spaces equipped with a doubling measure. The main result gives characterizations for mappings that preserve BMO. This extends the corresponding Euclidean results by Gotoh to metric measure spaces.
