(particle physics)
In superstring theory, a point, curve, surface, or higher-dimensional surface to which the end points of strings can be attached; its existence is implied by string duality.

It's known in the literature that there are many different but physically equivalent descriptions of how a D1-brane may end on a D3-brane.
Consequently, by discussing explicitly the fluctuations and the potential of intersecting D1-D3 branes in D1-brane world volume theory we found that the system has Neumann boundary conditions and the end of the string can move freely on the brane for both zero and high modes of the overall transverse fluctuations case.
