Deformed Harmonic Oscillator Algebras (DHOA) are generated by four operators: two mutually adjoint a and a†, self-adjoint N, and the unity 1. The Bargmann-Hilbert space is defined as a space of functions, holomorphic in a ring of the complex plane,

Generalizing the case of the usual harmonic oscillator, we look for Bargmann representations corresponding to deformed harmonic oscillators. Deformed harmonic oscillator algebras are generated by four operators a, a †, N and the unity 1 such as [a,

The R-matrix method is applied to the one-dimensional oscillator group. The resulting quantum groups and dual algebras are characterized. It is shown that both bosonic and fermionic dual algebras occur and that true deformations of the bosonic and fe

An analysis is presented of the cohomological underpinnings for the Weyl group of the canonical commutation relations on manifolds of constant negative curvature. Several uniqueness results are obtained leading from purely classical considerations to

TheR-matrix method is systematically applied to get several Heisenberg quantum groups depending on two or three parameters. It turns out that the associatedR-matrices have to verify a weaker form of the QYBE. Only for particular cases of quantum grou

Representations of the quantum algebra suq(2) are constructed in terms of q‐special functions, defined on real O(3) spheres and real planes. They include q‐Vilenkin functions, related to little q‐Jacobi functions, q‐spherical functions, and q

On studying various examples with one degree of freedom, we discuss the possibility of extending the classical concept of multi-Hamiltonian systems to the quantum domain. We show that an adaptation is possible in each case generally leading to distin

The most general second order evolution equation ψt+F(x,t,ψψ*,ψx,ψx*,ψxx, ψxx*)=0, invariant under the Galilei, Galilei‐similitude, and Schrodinger groups in two dimensions, is constructed. A preliminary step is a classification of all possi

The Bateman-Morse-Feshbach classical formulation of the damped oscillator is canonically quantized. The spectrum of the Hamiltonian is given. It is shown that the wavefunctions behave asymptotically as a superposition of damped oscillators when their
