Hello
Can some one tell me where to find something about the transformation properties of an n-dimensional delta function? S. Weinberg states in "Gravitation and Cosmology" that in four dimensions it behaves as a scalar with respect to Lorentz transformations, that is, if the Jacobian is 1 then the delta function expresed in the new coordenates is invariant(is expresed in the same form as in the old variables)
