In this note we study the world volume theory of pairs of D-brane and ghostD-brane, which is shown to have 16 linear supersymmetries and 16 nonlinearsupersymmetries. In particular we study a matrix model based on the pairs ofD(-1)-brane and ghost D(-1)-brane. Since such pairs are supposed to beequivalent to the closed string vacuum, we expect all 32 supersymmetries shouldbe unbroken. We show that the world volume theory of the pairs of D-brane andghost D-brane has unbroken 32 supersymmetries even though a half of them arenonlinearly realized.Comment: 12 pages, references adde
