Bose-Einstein Algebras

Definition

Bose-Einstein algebras are a class of operator algebras that arise in the study of quantum field theory, particularly in the representation of symmetries related to bosonic particles. These algebras generalize the notion of C*-algebras and von Neumann algebras, incorporating the statistical properties of bosons, which can occupy the same quantum state. They play a crucial role in understanding the structure of quantum field theories and the behavior of particles at a fundamental level.
