Arithmetic Bohr radius and Local Banach space theory

Abstract: This article introduces the notion of arithmetic Bohr radius for operator valued pluriharmonic functions on complete Reinhardt domains in $\mathbb{C}^n$. Using tools from local Banach space theory, we determine its asymptotic behavior in both finite and infinite dimensions. The framework developed in this article extends the classical Minkowski-space setting to a much broader class of sequence spaces, such as mixed Minkowski, Lorentz, and Orlicz spaces. This generality allows for a unified and systematic investigation of Bohr's theorem for both holomorphic and pluriharmonic functions.
