Topological tensor current of $\tilde{p}$-branes in the $\ddot{I}•$-mapping theory

Abstract

We present a new general topological tensor current of $\tilde{p}$-branes by making use of the $\ddot{I}•$-mapping theory. It is shown that the current is identically conserved and behave as $\hat{I}´(\vec{\ddot{I}}•),$ and every isolated zero of the vector field $\vec{\ddot{I}}•(x)$ corresponds to a `magnetic' $\tilde{p}$-brane. Using this topological current, the generalized Nambu action for multi $\tilde{p}$-branes is given, and the field strength $F$ corresponding to this topological tensor current is obtained. It is also shown that the `magnetic' charges carried by $\tilde{p}$-branes are topologically quantized and labeled by Hopf index and Brouwer degree, the winding number of the $\ddot{I}•$-mapping.
