Torons and D - brane bound states
نویسندگان
چکیده
We interpret instantons on a torus with twisted boundary conditions, in terms of bound states of branes. The interplay between the SU (N) and U (1) parts of the U (N) theory of N 4-branes allows the construction of a variety of bound states. The SU (N) and U (1) parts can contribute fractional amounts to the total instanton number which is integral.

Closed 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 کاملDelocalized Supergravity Solutions for Brane/Anti-brane Systems and their Bound States
We obtain various solutions for D = 4 dipoles and their bound states whose U(1) fields originate from various form fields in the effective string theories. We oxidize such dipole solutions to D = 10 to obtain delocalized supergravity solutions for the brane/anti-brane pairs and their bound states. We speculate on generalized harmonic superposition rules for supergravity solutions for (intersect...
متن کاملMatrix Theory and D - brane Bound States on Noncommutative T 4
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,...
متن کاملLong-distance interactions of D-brane bound states and longitudinal 5-brane in M(atrix) theory
We discuss long-distance, low-velocity interaction potentials for processes involving longitudinal M5-brane (corresponding in type IIA theory language to the 1/4 supersymmetric bound state of 4-brane and 0-brane). We consider the following scattering configurations: (a) D = 11 graviton off longitudinal M5-brane, or, equivalently, 0-branes off marginal 4‖0 bound state; (b) M2-brane off longitudi...
