On an Equivalent Norm on the Space BMO
Journal of Mathematical Sciences, 2018We extend the inequality proved by S. V. Bochkarev to a larger class of convolution operators assuming that the Fourier transforms of the kernels of these operators satisfy certain conditions in the spirit of the Hormander–Mikhlin multiplier theorem. Therefore, we give a new characterization of BMO.

It is known that the compactness of the commutators of point-wise multiplication with bilinear homogeneous Calderon–Zygmund operators acting on product of Lebesgue spaces is characterized by the multiplying function being in the space CMO.

Injectivity, the BMO norm and the universal Teichmüller space
Journal d'Analyse Mathématique, 1986In this paper, the crucial results on quasiconformal mappings are two distortion theorems. The first gives a Hölder estimate and the second a control over the measure distortion for mappings with small BMO-norm \(\| \log J_ f\|_*\) \((J_ f\) is the Jacobian determinant of f).

BMO and the Banach Space Approximation Problem
American Journal of Mathematics, 1985Let \(L^{\infty}=L^{\infty}(\partial D)\), \(H^{\infty}=H^{\infty}(D)\), \(BMO(\partial D)=the\) space of functions f on \(\partial D\) with \(\int^{2\pi}_{0}f(t)dt=0\) and \(\| f\|_{BMO}=\sup \{(\frac{1}{| I|}\int_{I}| f-f_ I|^ 2dt)^{1/2}:\) I an \(arc\subset \partial D\}

In this article, we study the boundedness of the fractional Rough Hardy operator and its adjoint operators on the central Morrey space with a variable exponent. We also establish the same boundedness for their commutators when the symbol functions are on
