摘要：

The potential between two separated D-instantons at fixed (super) space-time points is obtained by a simple explicit integration over the 'massive' variables of the zero-dimensional reduction of ten-dimensional U(2) super Yang-Mills theory. This potential vanishes for asymptotically large separations, becoming significant at separations of around the ten-dimensional Planck scale with a singularity at the origin, which is resolved by the extra 'massless' internal Yang-Mills super-coordinates.
