GEOMETRY OF DEFORMED BOSON ALGEBRAS
Keyword(s):
We consider a phase space realisation of an infinite parameter family of deformations of the boson algebra in which the q-deformed algebras arise as special cases. The deformation parameters are identified with coefficients of non-linear terms in the normal forms expansion of a family of classical Hamiltonian systems. These deformations simply correspond to nonlinear transformations of the boson algebra. They are physically interesting, as the deformed commutators consistently quantise a class of noncanonical classical Poisson structures.
