Are studied linear and quasilinear differential equations of elliptic, parabolic and ultraparabolic type in nondivergence and divergence form, Morrey spaces. Moreover, we study regularity properties of the gradient of local minima related to nonlinear functional, using some increases of functional, rather than the well known Euler equation associated with it.
