Abstract: | It is well known that the space-time coordinates
and the corresponding Dp-brane world-volume become non-commutative when the ends of the open string are attached to a Dp-brane with the Neveu-Schwarz background field
. In this paper, we extend these considerations by including an additional dilaton field
, linear in
. In that case, the conformal part of the world-sheet metric becomes a new non-commutative variable, while the coordinate
in the direction orthogonal to the hyper plane
becomes commutative.
