GENERALIZED COMMUTATION RELATIONS AND NONLINEAR MOMENTA THEORIES: A CLOSE RELATIONSHIP

摘要

A revision of generalized commutation relations is performed, besides a description of nonlinear momenta realization included in some DSR theories. It is shown that these propositions are closely related, specially we focus on Magueijo–Smolin momenta and Kempf et al. and Chang generalized commutators. Due to this, a new algebra arises with its own features that is also analyzed.
