locally compact quantum groups from von Neumann/- algebras with Haar measures
0.1 Hilbert spaces, Von Neumann algebras and Quantum Groups
John von Neumann introduced a mathematical foundation for Quantum Mechanics in the form of -algebras (http://planetmath.org/WeakHopfCAlgebra2) of (quantum) bounded operators in a (quantum:= presumed separable, i.e. with a countable basis) Hilbert space . Recently, such von Neumann algebras, (http://planetmath.org/WeakHopfCAlgebra2) and/or (more generally) C*-algebras are, for example, employed to define locally compact quantum groups (http://planetmath.org/LocallyCompactQuantumGroup) by equipping such algebras with a co-associative multiplication (http://planetmath.org/WeakHopfCAlgebra2) and also with associated, both left– and right– Haar measures, defined by two semi-finite normal weights [1].
0.1.1 Remark on Jordan-Banach-von Neumann (JBW) algebras,
A Jordan–Banach algebra (a JB–algebra for short) is both a real Jordan algebra and a Banach space, where for all , we have the following.
A JLB–algebra is a –algebra together with a Poisson bracket for which it becomes a Jordan–Lie algebra for some . Such JLB–algebras often constitute the real part of several widely studied complex associative algebras. For the purpose of quantization, there are fundamental relations between , JLB and Poisson algebras (http://planetmath.org/JordanBanachAndJordanLieAlgebras).
Definition 0.1.
A JB–algebra which is monotone complete and admits a separating set of normal sets is called a JBW-algebra.
These appeared in the work of von Neumann who developed an orthomodular lattice theory of projections on on which to study quantum logic. BW-algebras have the following property: whereas is a J(L)B–algebra, the self-adjoint part of a von Neumann algebra is a JBW–algebra.
