    "abstract": "Within the frame of kinetic theory a response function is derived for finite\nFermi systems which includes dissipation in relaxation time approximation and a\ncontribution from additional chaotic processes characterized by the largest\nLyapunov exponent. A generalized local density approximation is presented\nincluding the effect of many particle relaxation and the additional chaotic\nscattering. For small Lyapunov exponents relative to the product of wave vector\nand Fermi velocity in the system, the largest Lyapunov exponent modifies the\nresponse in the same way as the relaxation time. Therefore the transport\ncoefficients can be connected with the largest positive Lyapunov exponent in\nthe same way as known from the transport theory in relaxation time\napproximation.",
