Homogeneous Triebel-Lizorkin Spaces on Stratified Lie Groups

Journal of Function Spaces and Applications, 2013
Homogeneous Triebel-Lizorkin spaces with full range of parameters are introduced on stratified Lie groups in terms of Littlewood-Paley-type decomposition.

Homogeneous spaces with symmetries

, 2011
We give a brief survey of main recent results about invariant pseudo-Riemannian metrics and classical affinor structures on homogeneous spaces with symmetries obtained by the participants of the joint BRFFI-RFFI project “Homogeneous spaces with ...

Boundedness of sublinear operators on the homogeneous Herz spaces [PDF]

, 2003
Some boundedness results are established for sublinear operators on the homogeneous Herz spaces. As applications, some new theorems about the boundedness on homogeneous Herz spaces for commutators of singular integral operators are ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

Advanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

On chiral differential operators over homogeneous spaces

International Journal of Mathematics and Mathematical Sciences, 2001
We give a classification and construction of chiral algebras of differential operators over semisimple algebraic groups G and over homogeneous spaces G/N and G/P where N is a nilpotent and P a parabolic subgroup.

A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Isometries between spaces of homogeneous polynomials [PDF]

, 2005
We derive Banach–Stone theorems for spaces of homogeneous polynomials. We show that every isometric isomorphism between the spaces of homogeneous approximable polynomials on real Banach spaces E and F is induced by an isometric isomorphism of E′ onto F′.
