Summary
Quantum algebras are the universal algebras, associated to a finite-dimensional vector space and its endomorphisms. The Fermi or Bose statistics of a quantum algebra reflects the (anti-)symmetry of the basic-space dual product. The relation to the universal enveloping algebra of the basic endomorphisms and to the dual-product Clifford algebra is discussed together with its invariants. According to the Abelian or non-Abelian basic-space endomorphism algebra, it carries two different trace-induced linear forms-the Fock and the Heisenberg form, respectively. With a quantum algebra conjugation,e.g. connected with a-not necessarily Euclidean unitary-time representation, quantum algebras have an inner product and, in the case of a positive conjugation, a Hilbert space of Fock type for the Abelian and of Heisenberg type for the non-Abelian case.
