Sales, J. H.O.Suzuki, A. T.Zambrano, G. E.R. [UNESP]2022-04-292022-04-292004-12-02AIP Conference Proceedings, v. 739, p. 705-707.1551-76160094-243Xhttp://hdl.handle.net/11449/228345We use the light-front machinery to study the behavior of a relativistic free particle and obtain the quantum commutation relations from the classical Poisson brackets. We argue that the usual projection onto the light-front coordinates for these from the covariant commutation ralations does not reproduce the expected results.705-707engTrabalho apresentado em evento10.1063/1.18436992-s2.0-85020755608
