Although describing very different physical systems, both the Klein–Gordon equation for tachyons (m2<0) and the Helmholtz equation share a remarkable property: a unitary and irreducible representation of the corresponding invariance group on a suit

In this paper, we exploit the formal equivalence of the Solution Manifold of two distinct physical systems to create enough symmetries so as to characterize them by Noether Invariants, thus favoring their future quantization. In so doing, we somehow

We propose a new inner product for scalar fields that are solutions of the Klein-Gordon equation with m(2) < 0. This inner product is nonlocal, bearing an integral kernel including Bessel functions of the second kind. The associated norm proves to be

We perform the momentum-space quantization of a spin-less particle moving on the SU(2) group manifold, that is, the three-dimensional sphere S-3, by using a non-canonical method entirely based on symmetry grounds. To achieve this task, non-standard (

In this paper we achieve the quantization of a particle moving on the $SU(2)$ group manifold, that is, the three-dimensional sphere $S^{3}$, by using group-theoretical methods. For this purpose, a fundamental role is played by contact, non-point symm

Some SO(2, 1) invariant systems, like the Poschl-Teller potential (both trigonometric and hyperbolic) and the Morse potential are studied by means of a transformation relating their phase-spaces with the coadjoint orbits of SO(2, 1) or SO(3). The geo

There are many approaches for the description of dissipative systems coupled to some kind of environment. This environment can be described in different ways; only effective models will be considered here. In the Bateman model, the environment is rep
