  In order to understand the dynamical mechanism of the friction phenomena, we
heavily rely on the numerical analysis using various methods: molecular
dynamics, Langevin equation, lattice Boltzmann method, Monte Carlo, e.t.c.. We
propose a new method which has the following characteristic points: 1) the
geometrical approach to the statistical mechanical system; 2) the continuum
approach using Feynman's path integral (generalized version); 3) the
holographic (higher-dimensional) approach; 4) the renormalization phenomenon
takes place in order to treat the statistical fluctuation.
