Query: Dimensional Reduction of the Generalized DBI   We study the generalized Dirac-Born-Infeld (DBI) action, which describes a
$q$-brane ending on a $p$-brane with a ($q$+1)-form background. This action has
the equivalent descriptions in commutative and non-commutative settings, which
can be shown from the generalized metric and Nambu-Sigma model. We mainly
discuss the dimensional reduction of the generalized DBI at the massless level
on the flat spacetime and constant antisymmetric background in the case of flat
spacetime, constant antisymmetric background and the gauge potential vanishes
for all time-like components. In the case of $q=2$, we can do the dimensional
reduction to get the DBI theory. We also try to extend this theory by including
a one-form gauge potential.
