| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. In string theory,
D-branes are a class of extended objects upon which open strings can end
with Dirichlet boundary conditions, after which they are named. D-branes
were discovered by Dai, Leigh and Polchinski, and independently by
Horava in 1989. In 1995, Polchinski identified D-branes with black
p-brane solutions of supergravity, a discovery that triggered the Second
Superstring Revolution and led to both holographic and M-theory
dualities. D-branes are typically classified by their dimension, which
is indicated by a number written after the D. A D0-brane is a single
point, a D1-brane is a line (sometimes called a "D-string"), a D2-brane
is a plane, and a D25-brane fills the highest-dimensional space
considered in bosonic string theory. There are also instantonic
D(-1)-branes, which are localized in both space and time. |
