noun. Any of the spatially extended mathematical objects of zero or more dimensions used in string theory. A one-dimensional brane, referred to as a “1-brane,” is a string.

noun. A hypothetical object extending across a number of (often specified) spatial dimensions, with strings in string theory seen as one-dimensional examples.

"This treatment, of course, assumes the recovery of the Kerr metric in brane-worlds which we have found to the first order in the ratio of the brane separation to the radius of the AdS$_5$, $ (ell/r) $."
