    Me present a procedure for finding the exact solution to the linear-response Boltzmann equation for two-dimensional anisotropic systems and demonstrate it on examples of noncrystalline anisotropic magnetoresistance in a system with spin-orbit interaction. We show that two decoupled integral equations must be solved in order to find the nonequilibrium distribution function up to linear order in the applied electric field.

    Je prezentován způsob jak přesně řešit Boltzmannovu rovnici v anizotropních 2D systémech. Jako přiklad použití je spočítána nekrystalická anizotropní magnetorezistence v jednoduchých systémech se spin-orbitální interakcí.
