Query: Gauge symmetries decrease the number of Dp-brane dimensions. II.
  Inclusion of the Liouville term   The presence of the antisymmetric background field $B_{\mu\nu}$ leads to the
noncommutativity of the Dp-brane manifold, while the linear dilaton field in
the form $\Phi(x)=\Phi_0+a_\mu x^\mu$, causes the appearance of the commutative
Dp-brane coordinate, $x_c=a_\mu x^\mu$. In the present article we consider the
case where the conformal invariance is realized by inclusion of the Liouville
term. Then, the theory is conformally invariant even in the presence of the
world sheet conformal factor $F$, and it depends on the new parameter, the
central charge $c$. As well as in the absence of the Liouville action, for
particular relations between background fields, the local gauge symmetries
appear in the theory. They turn some Neumann boundary conditions into the
Dirichlet ones, and decrease the number of the Dp-brane dimensions.
