Query: Dual Actions for Born-Infeld and Dp-Brane Theories   Dual actions with respect to U(1) gauge fields for Born-Infeld and $Dp$-brane
theories are reexamined. Taking into account an additional condition, i.e. a
corollary to the field equation of the auxiliary metric, one obtains an
alternative dual action that does not involve the infinite power series in the
auxiliary metric given by ref. \cite{s14}, but just picks out the first term
from the series formally. New effective interactions of the theories are
revealed. That is, the new dual action gives rise to an effective interaction
in terms of one interaction term rather than infinite terms of different
(higher) orders of interactions physically. However, the price paid for
eliminating the infinite power series is that the new action is not quadratic
but highly nonlinear in the Hodge dual of a $(p-1)$-form field strength. This
non-linearity is inevitable to the requirement the two dual actions are
equivalent.
