Matrix Theory and D - brane Bound States on Noncommutative T 4

چکیده
We study D-brane bound states with a non-Abelian background on noncommutative T. We construct twisted quantum bundles and adjoint sections describing D-brane bound states. It is shown that the noncommutative T with non-Abelian backgrounds also exhibits SO(4, 4|Z) duality and the action of this group gives Morita equivalent T on which only D0-branes exist. For a reducible non-Abelian background, the moduli space of D-brane bound states in Type II string theory takes the form ∏ a(T )/Sqa .

Twisted Bundles on Noncommutative T and D-brane Bound States
We construct twisted quantum bundles and adjoint sections on noncommutative T, and investigate relevant D-brane bound states with non-Abelian backgrounds. We also show that the noncommutative T with non-Abelian backgrounds exhibits SO(4, 4|Z) duality and via this duality we get a Morita equivalent T on which only D0-branes exist. For a reducible non-Abelian background, the moduli space of D-bra...
متن کامل0 UG - 00 - 20 Spin ( p + 1 , p + 1 ) Covariant D p – brane Bound States
We construct Spin(p+1, p+1) covariant Dp–brane bound states by using that the potentials in the RR sector of toroidically compactified type II supergravity transform as a chiral spinor of the T–duality group. As an application, we show the invariance of the zero–force condition for a probe D–brane under noncommutative deformations of the background, which gives a holographic proof of the stabil...
متن کاملClosed String Brane-Like States, Brane Bound States and Noncommutative Branes
We study the mass and different RR charge distributions of the BPS (p,p-2)-brane bound states in the closed string brane-like σ-model. We show that such brane bound states can be realized by introducing a constant B field in the closed string theory. In addition we show that the worldvolume coordinates of these brane bound states turn out to be noncommutative. ∗ E-mail:polyakov,[email protected]...
متن کاملInstantons in the U(1) Born-Infeld Theory and Noncommutative Gauge Theory
We derive a BPS-type bound for maximally rotational symmetric configurations in four-dimensional Born-Infeld action with constant B field background. The supersymmetric configuration saturates this bound and is regarded as an analog of instanton in U(1) gauge theory. Furthermore, we find the explicit solutions of this BPS condition. These solutions have a finite action proportional to the insta...
متن کاملInstanton in Born-Infeld Action and Noncommutative Gauge Theory
We derive a BPS-type bound for four-dimensional Born-Infeld action with constant B field background. The supersymmetric configuration saturates this bound and is regarded as an analog of instanton in U(1) gauge theory. Furthermore, we find the explicit solutions of this BPS condition. These solutions have a finite action proportional to the instanton number and represent D(p−4)-branes within a ...
