  Gauge theory approach to consideration of the Nambu-Goldstone bosons as gauge
and vector fields represented by the Cartan forms of spontaneously broken
symmetries, is discussed. The approach is generalized to describe the
fundamental branes in terms of $(p+1)$-dimensional worldvolume gauge and
massless tensor fields consisting of the Nambu-Goldstone bosons associated with
the spontaneously broken Poincare symmetry of the $D$-dimensional Minkowski
space.
