Double phase meets Muckenhoupt
Daviti Adamadze, Lars Diening, Tengiz Kopaliani +1
In this paper we generalize the famous result of [FKS] to the double phase model. In particular, we work with minimal assumptions on the modulating coefficient by introducing a Muc…

Maximal operator on variable exponent spaces
Daviti Adamadze, Lars Diening, Tengiz Kopaliani
We explore the boundedness of the Hardy-Littlewood maximal operator on variable exponent spaces. Our findings demonstrate that the Muckenhoupt condition, in conjunction with Ne…
