In this respect, the vector-operators [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] satisfy the Bose commutation relations as:
p+1,q] and found simple commutation relations in [Cl.
The articles include Karasev's "Noncommutative Algebras, Nanostructures, and Quantum Dynamics Generated by Resonances," Karasev and Novikova's "Algebras with Polynomial Commutation Relations for a Quantum Particle in Electric and Magnetic Fields," Vorobjjev's "Poisson Structures and Linear Euler Systems over Symplectic Manifolds," and also his "Poisson Equivalence over a Symplectic Leaf.
The first is the canonical commutation relations of the infinite-dimensional Heisenberg algebra, or oscillator algebra.
They cover the structure of the space of the physical states, inequivalent representations of the canonical commutation relations, the spontaneous breakdown of symmetry and the Goldstone theorem, the dynamical rearrangement of symmetry and macroscopic manifestations of quantum field theory, thermal field theory and trajectories in the space of the representations, selected topics in thermal field theory, topological defects as non-homogeneous condensates, and dissipation and quantization.
The idea is to reduce the conditions we get from the Jacobi identities to some well-known commutation relations.
