Abstract: | An analytical-numerical integration method for the generalized Liouville equation is proposed and analyzed. Taking into account a Cauchy condition f(q,p,t)|t=0=f0(q,p) for the phase space distribution function, we constructed the problem solution as series expansion in time variable t using orthogonal polynomials and Hermite function. Also we proved the corresponding convergence theorems under certain boundedness conditions upon a Liouville operator. |
