Born-Infeld Lagrangian using Cayley-Dickson algebras

Abstract

We rewrite the Born-Infeld Lagrangian, which is originally given by the determinant of a $4\times 4$ matrix composed of the metric tensor $g$ and the field strength tensor $F$, using the determinant of a $(4\cdot 2^n)\times (4\cdot 2^n)$ matrix $H_{4\cdot 2^n}$. If the elements of $H_{4\cdot 2^n}$ are given by the linear combination of $g$ and $F$, it is found, based on the representation matrix for the multiplication operator of the Cayley-Dickson algebras, that $H_{4\cdot 2^n}$ is distinguished by a single parameter, where distinguished matrices are not similar matrices. We also give a reasonable condition to fix the paramete
