Bounded symmetric domains

Definition

Bounded symmetric domains are specific types of mathematical structures that arise in the study of several complex variables and complex geometry. These domains are defined as bounded subsets of complex spaces that possess a rich symmetry, typically characterized by a transitive action of a group on the domain. This concept is crucial in understanding Jordan triple systems, as these domains can be used to describe certain algebraic structures and relationships within the context of non-associative algebra.
