我们证明了所有超对称型IIAD-膜都可以构造为一定数量的不稳定非超对称型IIAD9-膜的束缚态。这种弦理论构造证明了时空流形X上IIA型理论中的D-膜电荷是由Witten最近提出的高K-理论群K^(-1)X分类的。具体地说，对于任何N，可以获得N个D0-膜的系统，根据16个IIA D9-膜。这表明，矩阵理论的动力学包含在16个不稳定的D9膜的世界体积上的磁涡物理中，这些不稳定的D9膜在低能下由U(16)规范理论描述。
We show that all supersymmetric Type IIA D-branes can be constructed as bound states of a certain number of unstable non-supersymmetric Type IIA D9-branes. This string-theoretical construction demonstrates that D-brane charges in Type IIA theory on spacetime manifold X are classified by the higher K-theory group K^(-1)X, as suggested recently by Witten. In particular, the system of N D0-branes can be obtained, for any N, in terms of sixteen Type IIA D9-branes. This suggests that the dynamics of Matrix theory is contained in the physics of magnetic vortices on the worldvolume of sixteen unstable D9-branes, described at low energies by a U(16) gauge theory.
