A boundedness criterion for averaging operators in variable exponent spaces of periodic functions
O. L. Vinogradov Saint Petersburg State University
Abstract:
A criterion for the uniform boundedness of Steklov averaging operators in variable exponent spaces of periodic functions is obtained. This criterion coincides with the known local analog of the Muckenhoupt condition. The boundedness of Steklov averages was previously known under the Dini–Lipschitz condition. The norms of averaging operators are estimated explicitly.
Key words and phrases:
variable exponent spaces, Steklov averages.
