Abstract
We propose a nonAbelian BornInfeld theory based on an Abelian theory by Erwin Schrodinger that, as he showed, is equivalent to BornInfeld theory. Its construction does not require at any stage the square root structure that characterizes the DiracBornInfeld (DBI) action. Various nonAbelian generalizations are possible. We focus our attention, in this work, in one of them. For it, it is shown that Instantons solutions exist.Our formalism could be of interest in connection with string theory and possible extensions of well known physical results in the usual BornInfeld Abelian case.
Keywords: BornInfeld; NonAbelian.
Resumen
Se propone una teoría noAbeliana de BornInfeld basada en una teoría Abeliana de Erwin Schrodinger que, como él lo ha mostrado, es equivalente a la teoría propuesta por Born e Infeld. Su construcción no requiere en ninguna etapa de la estructura de raíz cuadrada que caracteriza la acción DiracBornInfeld (DBI). Varias generalizaciones no Abelianas son posibles; nos centramos en este trabajo en una de ellas. Para esto, se muestra que las soluciones de Instantones existen. Nuestro formalismo puede ser de interés en conexión con teoría de cuerdas y posibles extensiones de resultados físicos bien conocidos en el caso de BornInfeld Abeliano usual.
Descriptores: BornInfeld; noAbeliano.

12. As is well known, in the usual BornInfeld theory the square root can be avoided by introducing an auxiliary field. Its equation of motion, when substituted in the modified action gives once more the square root structure. See M. Rocek and A.A. Tseytlin, Phys. Rev. D 59 (1999) 106001. The proposal here is, however, completely different. [ Links ]

15. Probably one of these two possibilities could be more appropiate to search them in connection with string theory, because it is argued that the open string effective Lagrangian should have (at tree level) a single trace (or symmetrized trace) over the group indices.
