A D-Brane is a strongly-coupled sort of an ${n}$-dimensional generalisation of an F1 String. What are some of the simple properties of an F1 String?

  • Weak coupling.
  • 1-Dimensional.

A D-Brane is strongly - coupled, (i.e. with $g_s>1$); and is $n$-dimensional.

The need for D-Branes

See, for example, this article. To summarise the main points, one needs D-Branes because:

  • T-Duality; exchanges Newmann (Free) boundary conditions with Dirchilet (Bound to Branes) boundary conditions, which means that Newmann Open Strings, in say, Type I String Theory, is by T-Duality, mapped to Dirchilet Open Strings, in it's T-Dual. If there are open strings (there are in the Type I), there must be D-Branes.
  • If one sees the worldsheets in a Ramond - Ramond Potential, it doesn't couple. To get around this, one must accept D-Branes.
