Uniform boundedness and compactness for the commutator of an extension of Riesz transform on stratified Lie groups

open access: yesAdvances in Nonlinear Analysis
Let G{\mathcal{G}} be a stratified Lie group, and let {Xj}1≤j≤n1{\left\{{X}_{j}\right\}}_{1\le j\le {n}_{1}} be a basis of the left-invariant vector fields of degree one on G{\mathcal{G}} and Δ=−∑j=1n1Xj2\Delta =-{\sum }_{j=1}^{{n}_{1}}{X}_{j}^{2} be the

A limiting case in partial regularity for quasiconvex functionals

open access: yesMathematics in Engineering
Local minimizers of nonhomogeneous quasiconvex variational integrals with standard $ p $-growth of the type $ w\mapsto \int \left[F(Dw)-f\cdot w\right]{\,{{\rm{d}}}x} $ feature almost everywhere $ \mbox{BMO} $-regular gradient provided that ...

On representation of solutions to the heat equation

open access: yesComptes Rendus. Mathématique
We propose a simple method to obtain semigroup representation of solutions to the heat equation using a local $L^2$ condition with prescribed growth and a boundedness condition within tempered distributions.

BMO Boundedness for Banach Space Valued Singular Integrals

open access: yesAnalysis in Theory and Applications, 2011
Summary: We consider a class of Banach space valued singular integrals. The \(L^p\) boundedness of these operators is obtained. The paper discusses their boundedness from BMO to BMO. As applications, we get BMO boundedness for the classic \(g\)-function and the Marcinkiewicz integral. Some known results are improved.
