Remarks on an Exact Seiberg-Witten map
We obtain the leading derivative corrections to an expression for the
Seiberg-Witten map given by Banerjee and Yang and show how they affect the
noncommutative deformation of the Maxwell action, as well as the matter
coupling in noncommutative emergent gravity.Comment: 8 page
B fields from a Luddite perspective
In this talk we discuss the geometric realization of B fields and higher
p-form potentials on a manifold M as connections on affine bundles over M. We
realize D branes on M as special submanifolds of these affine bundles. As an
application of this geometric understanding of the B field, we give a simple
geometric explanation for the Chern-Simons modification of the field strength
of the B field.Comment: 7 pages. From a talk given at the 3rd International Symposium on
