Abstract

We consider the motion of a particle described by an action that is a functional of the one–dimensional metric of the worldline and its first Frenet–Serret [FS] curvature. The metric and the curvature along with the orthogonal [FS] basis which connect them to the embedding functions defining the worldline are introduced as auxiliary variables by adding appropiate constraints. The conserved stress tensor associated with the theory is established in terms of the constraints.

Keywords: Relativistic particle.

 

Resumen

Se considera el movimiento de una partícula descrita por una acción que es una funcional de la métrica unidimensional de la línea de mundo y su primera curvatura de Frenet–Serret [FS]. La métrica y la curvatura junto con la base ortonormal FS que las conecta con las funciones de inmersión que definen la línea de mundo se introducen como variables auxiliares anadiendo constricciones adecuadas. El tensor de esfuerzos conservado asociado a la teoría se establece en términos de las constricciones.

Descriptores: Partícula relativista.
