Characterizations of Pluriharmonic Bloch Functions and Composition Operators in Bounded Symmetric Domains

Let \(\mathbb {B}_X\) ${\mathbb{B}}_X$ be a bounded symmetric domain realized as the open unit ball of a JB*-triple X. First, we extend the definition for pluriharmonic Bloch functions to \(\mathbb {B}_X\) ${\mathbb{B}}_X$ by using the infinitesimal Kobayashi metric. Next, we develop some methods to investigate Bloch functions, and composition operators of pluriharmonic Bloch spaces on bounded symmetric domains. The obtained results provide the improvements and extensions of the corresponding known results.
