By using the Nevanlinna theory of value distribution, we investigate the existence of solutions of some types of non-linear  q -difference differential equations. In particular, we generalize the Rellich–Wittich-type theorem and Malmquist-type theorem about differential equations to the case of  q -difference differential equations (system).

The existence of solutions of q-difference-differential equations
