ResumoWe propose that the natural lagrangian density fr a Kaluza-Klein theory in D = 2N+2 and 2N+3 dimensions, with an internal homogeneous space G/H, is the Euler-Poincaré density in 2N dimensions. When reduced to spacetime such an action is free from the cosmological term and it contains the Einstein-Yang-Mills action as well as additional interactions involving gauge fields and gravity.
