Brane - Wikipedia
In string theory and related theories (such as supergravity theories), a brane is a physical object that generalizes the notion of a zero-dimensional point particle, a one-dimensional string, or a …

2023年7月1日 · fundamental p p-branes (as in “fundamental particle”): these are given by sigma-models on (p + 1) (p+1)-dimensional worldvolumes describing propagation of single p p …
A p-brane is simply any object of p-dimensional spatial extent. Thus a 0-brane is a point particle, whereas a string is a 1-brane. The etymological root of “brane” is “membrane”, the case p =2. …
