TL;DR

This paper introduces a new topological tensor current for $ ilde{p}$-branes using $$-mapping theory, revealing their topological quantization and providing a generalized action for multiple branes.

Contribution

It develops a novel topological tensor current for $ ilde{p}$-branes and links their magnetic charges to topological invariants like Hopf index and Brouwer degree.

Findings

The tensor current is conserved and behaves as a delta function at zero points of $$.

Magnetic charges of $ ilde{p}$-branes are topologically quantized.

A generalized Nambu action for multi $ ilde{p}$-branes is formulated.

Abstract

We present a new general topological tensor current of $\tilde{p}$-branes by making use of the $\phi $-mapping theory. It is shown that the current is identically conserved and behave as $\delta (\vec{\phi}),$ and every isolated zero of the vector field $\vec{\phi}(x)$ 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 $\phi$-mapping.
