Mathematical models of the dynamics of elastoplastic, granular, and porous media are reduced to variational inequalities for hyperbolic differential operators that are thermodynamically consistent in the sense of Godunov. On this basis, the concept o

We consider the non-stationary problem on perturbation of a plane liquid crystal layer by electric field created by charges on the capacitor plates. The plates are disposed periodically on upper and lower sides along the liquid crystal layer. When so
