Abstract
The energy method is used to study some support properties of local solutions of second-order nonlinear parabolic equations with non-isotropic nonlinearities with respect to the solution and its spatial derivatives. We establish such properties of local weak solutions as finite speed of propagations of the initial disturbances, the waiting time phenomenon, and stable localization. The conditions providing these effects are formulated in terms of local assumptions on the data and the character of nonlinearity of the equation under consideration.
