We illustrate an isomorphic description of the observable algebra for quantum mechanics in terms of functions on the projective Hilbert space, and its Hilbert space analog, with a noncommutative product with explicit coordinates and discuss the physical and dynamical picture. The isomorphism is then used as a base to essentially translate the differential symplectic geometry of the infinite dimensional manifolds onto the observable algebra as a noncommutative geometry, hence obtaining the latter from the physical theory itself. We have essentially an extended formalism of the Schrodinger versus Heisenberg picture which we try to describe mathematically as a coordinate map from the phase space, which we have presented argument to be seen as the quantum model of the physical space, to the noncommutative geometry as coordinated by the six position and momentum operators. The observable algebra is taken as an algebra of functions on the latter operators. We advocate the idea that the noncommutative geometry can be seen as an alternative, noncommutative coordinate, picture of quantum (phase) space. Issues about the kind of noncommutative geometry obtained are also explored.
We discuss the notion about physical quantities as having values represented by real numbers, and its limiting to describe nature to be understood in relation to our appreciation that the quantum theory is a better theory of natural phenomena than it
The phase space of a relativistic system can be identified with the future tube of complexified Minkowski space. As well as a complex structure and a symplectic structure, the future tube, seen as an eight-dimensional real manifold, is endowed with a
Noncommutative geometries generalize standard smooth geometries, parametrizing the noncommutativity of dimensions with a fundamental quantity with the dimensions of area. The question arises then of whether the concept of a region smaller than the sc
We present a reduction procedure for gauge theories based on quotienting out the kernel of the presymplectic form in configuration-velocity space. Local expressions for a basis of this kernel are obtained using phase space procedures; the obstruction
We study two-dimensional Hamiltonians in phase space with noncommutativity both in coordinates and momenta. We consider the generator of rotations on the noncommutative plane and the Lie algebra generated by Hermitian rotationally invariant quadratic
