We discuss the gauge theory approach to consideration of the Nambu Goldstone bosons as gauge and vector fields represented by the Cartan forms of spontaneously broken symmetries. 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.
