HIGHER ORDER NIELSEN’S FIELD EQUATIONS

Recently Nielsen’s field equations in the ordinary field theory and the higher order Nielsen’s equations in the generalized mechanics of discrete systems have been derived by the author. The aim of this work is to develop the higher order Nielsen’s field equations in the generalized field theory. Since it is the most important case that the Lagrangian density depends on only up to second-order derivatives, our study is limited just to this case.
