Regularity in generalized Morrey spaces of solutions to higher order nondivergence elliptic equations with VMO coefficients

Electronic Journal of Qualitative Theory of Differential Equations, 2019
We study the boundedness of the sublinear integral operators generated by Calderón–Zygmund operator and their commutators with $\mathit{BMO}$ functions on generalized Morrey spaces.

Generalized $g$-iterated fractional approximations by sublinear operators [PDF]

Applicationes Mathematicae, 2020
Summary: We study approximation of functions by sublinear positive operators with applications to several max-product operators under generalized \(g\)-iterated fractional differentiability. Our work is based on our generalized \(g\)-iterated fractional results about positive sublinear operators.

Au42(PET)32 Nanocluster Sensitizer Unlocks the Annihilator Potential of Rubrene, Enabling High‐Performance NIR‐to‐Visible Photon Upconversion

Angewandte Chemie, EarlyView.
A needle‐shaped gold nanocluster, Au42(PET)32, serves as a powerful triplet sensitizer, enabling rubrene to fully express its intrinsic annihilator capability (spin statistical factor f = 0.58). This sensitizer–annihilator pair achieves record‐high upconversion internal quantum yields of 21.4% (808 nm excitation) and 15.0% (936 nm excitation ...

Anisotropic Hardy Spaces of Musielak-Orlicz Type with Applications to Boundedness of Sublinear Operators

The Scientific World Journal, 2014
Let φ:ℝn×[0,∞)→[0,∞) be a Musielak-Orlicz function and A an expansive dilation. In this paper, the authors introduce the anisotropic Hardy space of Musielak-Orlicz type, HAφ(ℝn), via the grand maximal function.

Convergence rate analysis for averaged fixed point iterations in the presence of H\"older regularity

, 2016
In this paper, we establish sublinear and linear convergence of fixed point iterations generated by averaged operators in a Hilbert space. Our results are achieved under a bounded H\"older regularity assumption which generalizes the well-known notion of ...
