The boundedness of rough generalized commutators with Lipschitz functions on homogeneous variable exponent Herz type spaces (2506.12164v1)

Abstract: With the development of science, many nonlinear problems have emerged. At this time, the classical function space has certain restrictions. For example, it has lost its effectiveness for nonlinear problems under nonstandard growth conditions. In the process of studying such nonlinear problems, scholars are paying more and more attention to the transition from classical function space to variable exponent function space. Also, there is a big difference between variable exponent space and classical function space, mainly because variable exponent function space has lost translation invariance. This difference leads to many properties that hold in classical space no longer hold in variable exponent space. It is important to emphasize that variable exponent function spaces are a fundamental building block in harmonic analysis. In recent years, there has been a growing interest in the study of function spaces equipped with variable exponents, leading to the development of a new framework known as variable exponent analysis. These spaces provide a powerful tool for analyzing functions with variable growth or decay rates and have found applications in various areas of mathematics, including partial differential equations, harmonic analysis and image processing. One can better understand the heterogeneity and complexity inherent in many real world phenomena by taking into consideration the theory of variable exponent function spaces. Thus, by using certain properties of Lipschitz functions and variable exponents, in this article, we establish the boundedness of a class of rough generalized commutators with Lipschitz functions on homogeneous variable exponent Herz and Herz-Morrey spaces.
