On The Instanton Solutions Of The Self - Dual Membrane In Various Dimensions
We present some methods of determining explicit solutions for self-dual supermembranes in 4 + 1 and 8 + 1 dimensions with spherical or toroidal topology. For configurations of axial symmetry, the continuous SU(∞) Toda equation turns out to play a central role and a specific method of determining all the periodic solutions is suggested. A number of examples is studied in detail.
متن کاملThe Self - Dual String Soliton
We obtain a BPS soliton of the M theory fivebrane's equations of motion representing a supersymmetric self-dual string. The resulting solution is then dimensionally reduced and used to obtain 0-brane and (p − 2)-brane solitons on D-p-branes.
متن کاملSelf-dual fields harbored by a Kerr–Taub-bolt instanton
We present a new exact solution for self-dual Abelian gauge fields living on the space of the Kerr–Taub-bolt instanton, which is a generalized example of asymptotically flat instantons with non-self-dual curvature, by constructing the corresponding square integrable harmonic form on this space. 2005 Elsevier B.V.

متن کاملHigher Weights and Binary Self-Dual Codes
The theory of higher weights is applied to binary self-dual codes. Bounds are given for the second minimum higher weight and a Gleason type theorem is derived for the second higher weight enumerator. The second weight enumerator is shown to be unique for the putative 72; 36; 16] Type II code and the rst three minimum weights are computed for optimal codes of length less than 28. We connect them...
متن کاملSelf-Dual Nonsupersymmetric Type II String Compactifications
It has recently been proposed that certain nonsupersymmetric type II orbifolds have vanishing perturbative contributions to the cosmological constant. We show that techniques of Sen and Vafa allow one to construct dual type II descriptions of these models (some of which have no weakly coupled heterotic dual). The dual type II models are given by the same orbifolds with the string coupling S and...
