In section 3 the factorization of the hypergeometric-type difference equation is discussed, which is used in section 4 to construct a dynamical symmetry algebra in the case of the Charlier polynomials.
We] have shown that the dynamical symmetry associated with motion in [the relevant kind of force field] provides extremely stringent limits on any possible deviation of the number of dimensions from the integer value of 3, on both atomic and astronomical length scales," they conclude.
To identify the shape phases and their transition it is helpful to examine the correspondence between the interaction strengths in the microscopic model and the dynamical symmetry in the IBM.

The dynamical symmetry E(5) describe the phase transition between a spherical vibrator (U(5)) and [gamma]-soft rotor (O(6)) and the X(5) for the critical point of the spherical to axially deformed (SU(3)) transition.
It is well know that the dynamical symmetry associated with U(5) corresponds to a spherical shape [beta] = 0, the dynamical symmetry SU(3) is associated with an axially deformed shape [beta] [not equal to] 0 and [gamma] = 0, [pi]/3 and the dynamical symmetry O(6) is related to a y-unstable deformed shape [beta] [not equal to] 0 and [gamma]-independent.
The analysis of the three dynamical symmetry limits of the IBM provides a good test of the formalism presented in the previous section.
An ongoing confusion in physics is that absolute motion is incompatible with Lorentz symmetry, when the evidence is that it is the cause of that dynamical symmetry.
