2T Physics, Scale Invariance and Topological Vector Fields

Abstract: We construct, in classical two-time physics, the necessary structure for the most general configuration space formulation of quantum mechanics containing gravity in d + 2 dimensions. This structure is composed of a symmetric Riemannian metric tensor and of a vector field that defines a section of a flat U (1) bundle over space-time. This construction is possible because of the existence of a finite local scale invariance of the Hamiltonian and because two-time physics contains, at the classical level, a local … Show more

“…This paper also gives relevant contributions to the development of 2T physics with vector fields. In addition to the local scale invariance of the classical Hamiltonian equations of motion in the case when A M = A M (X) that was presented in [19], this paper also points out that the classical Hamiltonian equations of motion are invariant under local scale transformations in the case when A M = A M (P ). For each of the symmetries of the 2T action in the case when A M = A M (X) that were presented in [19], this paper also presents the corresponding symmetry with A M = A M (P ).…”

This existence of the same symmetries of the 2T action in position space and in momentum space is what gives support for the new quantum mechanical equations we write here.…”
