The asymptotic solution of the equation describing the polytropic gas filtration in a nonhomogeneous porous medium. 2

The asymptotic solution of the singulary perturbed boundary problem of degenerate parabolic equation describing the nonstationary polytropic gas filtration in a nonhomogeneous porous medium was constructed. The estimation of difference between the exact and asymptotic solution was given. It enables to verify the asymptotic solution.
