Fundamental Commutators in a Gravitational Field
W. Chagas-Filho
We show how an induced invariance of the massless particle action can be used to construct an extension of the Heisenberg canonical commutation relations in a non-commutative space…
New Heisenberg Relations in a Non-commutative Geometry
W. Chagas-Filho
We show how an induced invariance of the massless particle action can be used to construct an extension of the Heisenberg canonical commutation relations in a non-commutative space…
High Energy Commutators in Particle, String and Membrane Theories
W. Chagas-Filho
We study relativistic particle, string and membrane theories as defining field theories containing gravity in (0+1), (1+1) and (2+1) spacetime dimensions respectively. We show how…
Extended Conformal Algebra and Non-commutative Geometry in Particle Theory
W. Chagas-Filho
We show how an off shell invariance of the massless particle action allows the construction of an extension of the conformal space-time algebra and induces a non-commutative space-…
Relativistic Particles and Commutator Algebras
W. F. Chagas-Filho
We construct the vector fields associated to the space-time invariances of relativistic particle theory in flat Euclidean space-time. We show that the vector fields associated to t…
Free massless particles and extended space-time algebra
W. F. Chagas-Filho
We study the space-time invariances of the relativistic particle action for both the massive and massless cases. While the massive action has only the invariances associated to the…
